Another useful thing to do with numpy.histogram is to plot the output as the x and y coordinates on a linegraph. For example:

arr = np.random.randint(1, 51, 500)
y, x = np.histogram(arr, bins=np.arange(51))
fig, ax = plt.subplots()
ax.plot(x[:-1], y)
fig.show()

This can be a useful way to visualize histograms where you would like a higher level of granularity without bars everywhere. Very useful in image histograms for identifying extreme pixel values.

None of the solutions work if you just changed the permissions of a file (this is on DOS/Windoze)

If you want to have the result for all values of NUM:

SELECT `NUM`, COUNT(*) AS `count` 
FROM yourTable
GROUP BY `NUM`

Or just for one specific:

SELECT `NUM`, COUNT(*) AS `count` 
FROM yourTable
WHERE `NUM`=1

  $("#target").on({
        hover: function(){
           //do on mouse hover
        },  
        click: function(){
            //do on mouse click
        }  
    });

Select ColumnB and as two CF formula rules apply:

Green: =AND(B1048576="X",B1="Y")

Red: =AND(B1048576="X",B1="W")

You can use the workbook.get_worksheet_by_name() feature: https://xlsxwriter.readthedocs.io/workbook.html#get_worksheet_by_name

According to https://xlsxwriter.readthedocs.io/changes.html the feature has been added on May 13, 2016.

"Release 0.8.7 - May 13 2016

-Fix for issue when inserting read-only images on Windows. Issue #352.

-Added get_worksheet_by_name() method to allow the retrieval of a worksheet from a workbook via its name.

-Fixed issue where internal file creation and modification dates were in the local timezone instead of UTC."

I stumbled on this question while trying to do the same thing (I think). Here is how I did it:

df['index_col'] = df.index

You can then sort on the new index column, if you like.

Oracle 11g provides a PIVOT operation that does what you want.

Oracle 11g solution

select * from
(select id, k, v from _kv) 
pivot(max(v) for k in ('name', 'age', 'gender', 'status')

(Note: I do not have a copy of 11g to test this on so I have not verified its functionality)

I obtained this solution from: http://orafaq.com/wiki/PIVOT

EDIT -- pivot xml option (also Oracle 11g)
Apparently there is also a pivot xml option for when you do not know all the possible column headings that you may need. (see the XML TYPE section near the bottom of the page located at http://www.oracle.com/technetwork/articles/sql/11g-pivot-097235.html)

select * from
(select id, k, v from _kv) 
pivot xml (max(v)
for k in (any) )

(Note: As before I do not have a copy of 11g to test this on so I have not verified its functionality)

Edit2: Changed v in the pivot and pivot xml statements to max(v) since it is supposed to be aggregated as mentioned in one of the comments. I also added the in clause which is not optional for pivot. Of course, having to specify the values in the in clause defeats the goal of having a completely dynamic pivot/crosstab query as was the desire of this question's poster.

Maybe something like this:

yourformName.YourLabel.Font = new Font("Arial", 24,FontStyle.Bold);

Or if you are in the same class as the form then simply do this:

YourLabel.Font = new Font("Arial", 24,FontStyle.Bold);

The constructor takes diffrent parameters (so pick your poison). Like this:

Font(Font, FontStyle)   
Font(FontFamily, Single)
Font(String, Single)
Font(FontFamily, Single, FontStyle)
Font(FontFamily, Single, GraphicsUnit)
Font(String, Single, FontStyle)
Font(String, Single, GraphicsUnit)
Font(FontFamily, Single, FontStyle, GraphicsUnit)
Font(String, Single, FontStyle, GraphicsUnit)
Font(FontFamily, Single, FontStyle, GraphicsUnit, Byte)
Font(String, Single, FontStyle, GraphicsUnit, Byte)
Font(FontFamily, Single, FontStyle, GraphicsUnit, Byte, Boolean)
Font(String, Single, FontStyle, GraphicsUnit, Byte, Boolean)

Reference here

A comprehansive comparison between diffreent formats made by me in this post- https://maxondev.com/serialization-performance-comparison-c-net-formats-frameworks-xmldatacontractserializer-xmlserializer-binaryformatter-json-newtonsoft-servicestack-text/

Just one sample from the post-

To fix the issue:

protected void Application_PostAuthorizeRequest()
{
    System.Web.HttpContext.Current.SetSessionStateBehavior(System.Web.SessionState.SessionStateBehavior.Required);
}

in Global.asax.cs

You could also use the .add() function:

 df.loc[:,'variance'] = df.loc[:,'budget'].add(df.loc[:,'actual'])

by using Java 8 classes. we can manipulate date and time very easily as below.

LocalDateTime today = LocalDateTime.now();
LocalDateTime minusHours = today.minusHours(24);
LocalDateTime minusMinutes = minusHours.minusMinutes(30);
LocalDate localDate = LocalDate.from(minusMinutes);

Based on one of the other solutions with a flag to switch between weeks starting on Sunday or Monday

function getWeekForDate($date, $weekStartSunday = false){

    $timestamp = strtotime($date);

    // Week starts on Sunday
    if($weekStartSunday){
        $start = (date("D", $timestamp) == 'Sun') ? date('Y-m-d', $timestamp) : date('Y-m-d', strtotime('Last Sunday', $timestamp));
        $end = (date("D", $timestamp) == 'Sat') ? date('Y-m-d', $timestamp) : date('Y-m-d', strtotime('Next Saturday', $timestamp));
    } else { // Week starts on Monday
        $start = (date("D", $timestamp) == 'Mon') ? date('Y-m-d', $timestamp) : date('Y-m-d', strtotime('Last Monday', $timestamp));
        $end = (date("D", $timestamp) == 'Sun') ? date('Y-m-d', $timestamp) : date('Y-m-d', strtotime('Next Sunday', $timestamp));
    }

    return array('start' => $start, 'end' => $end);
}

I think creating a class to simulate C-like structs, like you've been doing, is the best way.

It's a great way to group related data and simplifies passing parameters to functions. I'd also argue that a JavaScript class is more like a C++ struct than a C++ class, considering the added effort needed to simulate real object oriented features.

I've found that trying to make JavaScript more like another language gets complicated fast, but I fully support using JavaScript classes as functionless structs.

You could use a VB Script I wrote exactly for this purpose: https://github.com/ezrarieben/mssql-backup-vbs/

Schedule a task in the "Task Scheduler" to execute the script as you like and it'll backup the entire DB to a BAK file and save it wherever you specify.

You don't have to use jQuery. Plain JavaScript will do. I wouldn't recommend any library that ports XML standards onto JavaScript, and I was frustrated that no other solution existed for this so I wrote my own library.

I adapted regex to work with JSON.

First, stringify the JSON object. Then, you need to store the starts and lengths of the matched substrings. For example:

"matched".search("ch") // yields 3

For a JSON string, this works exactly the same (unless you are searching explicitly for commas and curly brackets in which case I'd recommend some prior transform of your JSON object before performing regex (i.e. think :, {, }).

Next, you need to reconstruct the JSON object. The algorithm I authored does this by detecting JSON syntax by recursively going backwards from the match index. For instance, the pseudo code might look as follows:

find the next key preceding the match index, call this theKey
then find the number of all occurrences of this key preceding theKey, call this theNumber
using the number of occurrences of all keys with same name as theKey up to position of theKey, traverse the object until keys named theKey has been discovered theNumber times
return this object called parentChain

With this information, it is possible to use regex to filter a JSON object to return the key, the value, and the parent object chain.

You can see the library and code I authored at http://json.spiritway.co/

I had similar situation and here is my approach which is somewhat different:

 HADOOP_USER_NAME=hdfs hdfs dfs -put /root/MyHadoop/file1.txt /

What you actually do is you read local file in accordance to your local permissions but when placing file on HDFS you are authenticated like user hdfs. You can do this with other ID (beware of real auth schemes configuration but this is usually not a case).

Advantages:

1. Permissions are kept on HDFS.
2. You don't need sudo.
3. You don't need actually appropriate local user 'hdfs' at all.
4. You don't need to copy anything or change permissions because of previous points.

Ahhh, that's super simple, no programming required.

See: https://developers.facebook.com/docs/plugins/page-plugin

You'll want to keep the show stream option turned on. You can adjust width and heigth and a few other things.

There is also logging.exception.

import logging

...

try:
    g()
except Exception as ex:
    logging.exception("Something awful happened!")
    # will print this message followed by traceback

Output:

ERROR 2007-09-18 23:30:19,913 error 1294 Something awful happened!
Traceback (most recent call last):
  File "b.py", line 22, in f
    g()
  File "b.py", line 14, in g

(From http://blog.tplus1.com/index.php/2007/09/28/the-python-logging-module-is-much-better-than-print-statements/ via How to print the full traceback without halting the program?)

Is there any problem?

There are several issues:

• CString is a template specialization of CStringT. Depending on the BaseType describing the character type, there are two concrete specializations: CStringA (using char) and CStringW (using wchar_t).
• While wchar_t on Windows is ubiquitously used to store UTF-16 encoded code units, using char is ambiguous. The latter commonly stores ANSI encoded characters, but can also store ASCII, UTF-8, or even binary data.
• We don't know the character encoding (or even character type) of CString (which is controlled through the _UNICODE preprocessor symbol), making the question ambiguous. We also don't know the desired character encoding of std::string.
• Converting between Unicode and ANSI is inherently lossy: ANSI encoding can only represent a subset of the Unicode character set.

To address these issues, I'm going to assume that wchar_t will store UTF-16 encoded code units, and char will hold UTF-8 octet sequences. That's the only reasonable choice you can make to ensure that source and destination strings retain the same information, without limiting the solution to a subset of the source or destination domains.

The following implementations convert between CStringA/CStringW and std::wstring/std::string mapping from UTF-8 to UTF-16 and vice versa:

#include <string>
#include <atlconv.h>

std::string to_utf8(CStringW const& src_utf16)
{
    return { CW2A(src_utf16.GetString(), CP_UTF8).m_psz };
}

std::wstring to_utf16(CStringA const& src_utf8)
{
    return { CA2W(src_utf8.GetString(), CP_UTF8).m_psz };
}

The remaining two functions construct C++ string objects from MFC strings, leaving the encoding unchanged. Note that while the previous functions cannot cope with embedded NUL characters, these functions are immune to that.

#include <string>
#include <atlconv.h>

std::string to_std_string(CStringA const& src)
{
    return { src.GetString(), src.GetString() + src.GetLength() };
}

std::wstring to_std_wstring(CStringW const& src)
{
    return { src.GetString(), src.GetString() + src.GetLength() };
}

Pretty straight forward, use relative path

string[] offerFiles = Directory.GetFiles(Server.MapPath("~/offers"), "*.csv");

In my opinion errors have a reason to appear, that my sound stupid, but thats the way it is. Good programming only raises errors when you have to handle them. Also, as i read some time ago, "the pass-Statement is a Statement that Shows code will be inserted later", so if you want to have an empty except-statement feel free to do so, but for a good program there will be a part missing. because you dont handle the things you should have. Appearing exceptions give you the chance to correct input data or to change your data structure so these exceptions dont occur again (but in most cases (Network-exceptions, General input-exceptions) exceptions indicate that the next parts of the program wont execute well. For example a NetworkException can indicate a broken network-connection and the program cant send/recieve data in the next program steps.

But using a pass block for only one execption-block is valid, because you still differenciate beetween the types of exceptions, so if you put all exception-blocks in one, it is not empty:

try:
    #code here
except Error1:
    #exception handle1

except Error2:
    #exception handle2
#and so on

can be rewritten that way:

try:
    #code here
except BaseException as e:
    if isinstance(e, Error1):
        #exception handle1

    elif isinstance(e, Error2):
        #exception handle2

    ...

    else:
        raise

So even multiple except-blocks with pass-statements can result in code, whose structure handles special types of exceptions.

%d, 0 is FALSE, 1 is TRUE.

BOOL b; 
NSLog(@"Bool value: %d",b);

or

NSLog(@"bool %s", b ? "true" : "false");

On the bases of data type %@ changes as follows

For Strings you use %@
For int  you use %i
For float and double you use %f

in Swift 3,4 you should use "Compare". for example:

DateArray.sort { (($0)?.compare($1))! == .orderedDescending }

There are multiple ways of applying aggregate functions to multiple columns.

GroupedData class provides a number of methods for the most common functions, including count, max, min, mean and sum, which can be used directly as follows:

• Python:

  df = sqlContext.createDataFrame(
      [(1.0, 0.3, 1.0), (1.0, 0.5, 0.0), (-1.0, 0.6, 0.5), (-1.0, 5.6, 0.2)],
      ("col1", "col2", "col3"))
  
  df.groupBy("col1").sum()
  
  ## +----+---------+-----------------+---------+
  ## |col1|sum(col1)|        sum(col2)|sum(col3)|
  ## +----+---------+-----------------+---------+
  ## | 1.0|      2.0|              0.8|      1.0|
  ## |-1.0|     -2.0|6.199999999999999|      0.7|
  ## +----+---------+-----------------+---------+
  

• Scala

  val df = sc.parallelize(Seq(
    (1.0, 0.3, 1.0), (1.0, 0.5, 0.0),
    (-1.0, 0.6, 0.5), (-1.0, 5.6, 0.2))
  ).toDF("col1", "col2", "col3")
  
  df.groupBy($"col1").min().show
  
  // +----+---------+---------+---------+
  // |col1|min(col1)|min(col2)|min(col3)|
  // +----+---------+---------+---------+
  // | 1.0|      1.0|      0.3|      0.0|
  // |-1.0|     -1.0|      0.6|      0.2|
  // +----+---------+---------+---------+
  

Optionally you can pass a list of columns which should be aggregated

df.groupBy("col1").sum("col2", "col3")

You can also pass dictionary / map with columns a the keys and functions as the values:

• Python

  exprs = {x: "sum" for x in df.columns}
  df.groupBy("col1").agg(exprs).show()
  
  ## +----+---------+
  ## |col1|avg(col3)|
  ## +----+---------+
  ## | 1.0|      0.5|
  ## |-1.0|     0.35|
  ## +----+---------+
  

• Scala

  val exprs = df.columns.map((_ -> "mean")).toMap
  df.groupBy($"col1").agg(exprs).show()
  
  // +----+---------+------------------+---------+
  // |col1|avg(col1)|         avg(col2)|avg(col3)|
  // +----+---------+------------------+---------+
  // | 1.0|      1.0|               0.4|      0.5|
  // |-1.0|     -1.0|3.0999999999999996|     0.35|
  // +----+---------+------------------+---------+
  

Finally you can use varargs:

• Python

  from pyspark.sql.functions import min
  
  exprs = [min(x) for x in df.columns]
  df.groupBy("col1").agg(*exprs).show()
  

• Scala

  import org.apache.spark.sql.functions.sum
  
  val exprs = df.columns.map(sum(_))
  df.groupBy($"col1").agg(exprs.head, exprs.tail: _*)
  

There are some other way to achieve a similar effect but these should more than enough most of the time.

• The audio must be placed in the raw folder, if it doesn't exists, create one.
• The raw folder must be inside the res folder
• The name mustn't have any - or special characters in it.

On your activity, you need to have a object MediaPlayer, inside the onCreate method or the onclick method, you have to initialize the MediaPlayer, like MediaPlayer.create(this, R.raw.name_of_your_audio_file), then your audio file ir ready to be played with the call for start(), in your case, since you want it to be placed in a button, you'll have to put it inside the onClick method.

Example:

private Button myButton;
private MediaPlayer mp;
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.myactivity);
        mp = MediaPlayer.create(this, R.raw.gunshot);

        myButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mp.start();
            }
        });
}
}

The Spring documentation describes the following standard scopes:

singleton: (Default) Scopes a single bean definition to a single object instance per Spring IoC container.

prototype: Scopes a single bean definition to any number of object instances.

request: Scopes a single bean definition to the lifecycle of a single HTTP request; that is, each HTTP request has its own instance of a bean created off the back of a single bean definition. Only valid in the context of a web-aware Spring ApplicationContext.

session: Scopes a single bean definition to the lifecycle of an HTTP Session. Only valid in the context of a web-aware Spring ApplicationContext.

global session: Scopes a single bean definition to the lifecycle of a global HTTP Session. Typically only valid when used in a portlet context. Only valid in the context of a web-aware Spring ApplicationContext.

Additional custom scopes can also be created and configured using a CustomScopeConfigurer. An example would be the flow scope added by Spring Webflow.

By the way, you argues that you always used prototype what I find strange. The standard scope is singleton and in the application I develop, I rarely need the prototype scope. You should maybe take a look at this.

In javascript:

document.getElementById("myDIV").style.display = "none";

and in jquery:

$("#myDIV").css({display: "none"});
$("#myDIV").css({display: "block"});

and you can use:

$('#myDIV').hide();
$('#myDIV').show();

This occurs if the password for the database is not given.

The "I literally tried everything else" answer:

This problem will also occur if you don't have an upto date Android Support Library and Android Support Repository. Just install using the SDK manager.

I was able to install libc6 2.17 in Debian Wheezy by editing the recommendations in perror's answer:

IMPORTANT
You need to exit out of your display manager by pressing CTRL-ALT-F1. Then you can stop x (slim) with sudo /etc/init.d/slim stop

(replace slim with mdm or lightdm or whatever)

Add the following line to the file /etc/apt/sources.list:

deb http://ftp.debian.org/debian experimental main

Should be changed to:

deb http://ftp.debian.org/debian sid main

Then follow the rest of perror's post:

Update your package database:

apt-get update

Install the eglibc package:

apt-get -t sid install libc6-amd64 libc6-dev libc6-dbg

IMPORTANT
After done updating libc6, restart computer, and you should comment out or remove the sid source you just added (deb http://ftp.debian.org/debian sid main), or else you risk upgrading your whole distro to sid.

Hope this helps. It took me a while to figure out.

• process.cwd() returns directory where command has been executed (not directory of the node package) if it's has not been changed by 'process.chdir' inside of application.
• __filename returns absolute path to file where it is placed.
• __dirname returns absolute path to directory of __filename.

If you need to load files from your module directory you need to use relative paths.

require('../lib/test');

instead of

var lib  = path.join(path.dirname(fs.realpathSync(__filename)), '../lib');

require(lib + '/test');

It's always relative to file where it called from and don't depend on current work dir.

Adding android:autoSizeTextType="uniform" will resize the text for you automatically

And if you need to style your form elements according to it's state (modified/not modified) dynamically or to test whether some values has actually changed, you can use the following module, developed by myself: https://github.com/betsol/angular-input-modified

It adds additional properties and methods to the form and it's child elements. With it, you can test whether some element contains new data or even test if entire form has new unsaved data.

You can setup the following watch: $scope.$watch('myForm.modified', handler) and your handler will be called if some form elements actually contains new data or if it reversed to initial state.

Also, you can use modified property of individual form elements to actually reduce amount of data sent to a server via AJAX call. There is no need to send unchanged data.

As a bonus, you can revert your form to initial state via call to form's reset() method.

You can find the module's demo here: http://plnkr.co/edit/g2MDXv81OOBuGo6ORvdt?p=preview

This happens when a library is getting compiled twice (i.e it is added two time). It can be support library or any other, it doesn't matter.
The common case is that you have added a compile statement of a library which is already in your libs/ directory. All the *.jar files are compiled automatically. Thus, adding a compile statement is causing the error. Removing that statement might fix this issue. If this is not applicable then we already have some awesome answers.

Do the following steps:

1. Download the Flutter SDK Flutter SDK Archive

2. Extract it where do you want (for example /home/development/flutter)

3. Set your PATH, edit your file with this command gedit ~/.profile, you need to add this line

export PATH=[location_where_you_extracted_flutter]/flutter/bin:$PATH

I showed you above where I've extracted mine, so my export will look like this

export PATH=/home/myUser/development/flutter/bin:$PATH

4. Save the file and close it.
5. Run source ~/.profile to load the changes
6. If you run now flutter doctor should work!

I just make one for my own purpose. You may can use it as reference.

#!/bin/bash
cd /vzwhome/c0cheh1/dev_source/UB_14_8
for file in *
do
    echo $file
    cd "/vzwhome/c0cheh1/dev_source/UB_14_8/$file/Configuration/$file"
    echo "==> `pwd`"
    for subfile in *\ *; do [ -d "$subfile" ] && ( mv "$subfile" "$(echo $subfile | sed -e 's/ /_/g')" ); done
    ls
    cd /vzwhome/c0cheh1/dev_source/UB_14_8
done

Most of these answers are out of date.

Google now has an easy way to import it.. We will continue to see a lot of outdated information as they did not create this solution for a good 2-3 years.

All you need to do is add to your Build.Gradle the following:

compile 'com.android.volley:volley:1.0.0'

IE

apply plugin: 'com.android.application'

    compileSdkVersion 25
    buildToolsVersion "24.0.0"
    defaultConfig {

        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

    compile 'com.android.volley:volley:1.0.0'
    testCompile 'junit:junit:4.12'
}

It sounds like your database dump includes the information for creating the database. So don't give the MySQL command line a database name. It will create the new database and switch to it to do the import.

TLDR; _{Logical Operators in Pandas are &, | and ~, and parentheses (...) is important!}

Python's and, or and not logical operators are designed to work with scalars. So Pandas had to do one better and override the bitwise operators to achieve vectorized (element-wise) version of this functionality.

So the following in python (exp1 and exp2 are expressions which evaluate to a boolean result)...

exp1 and exp2              # Logical AND
exp1 or exp2               # Logical OR
not exp1                   # Logical NOT

...will translate to...

exp1 & exp2                # Element-wise logical AND
exp1 | exp2                # Element-wise logical OR
~exp1                      # Element-wise logical NOT

for pandas.

If in the process of performing logical operation you get a ValueError, then you need to use parentheses for grouping:

(exp1) op (exp2)

For example,

(df['col1'] == x) & (df['col2'] == y) 

And so on.

Boolean Indexing: A common operation is to compute boolean masks through logical conditions to filter the data. Pandas provides three operators: & for logical AND, | for logical OR, and ~ for logical NOT.

Consider the following setup:

np.random.seed(0)
df = pd.DataFrame(np.random.choice(10, (5, 3)), columns=list('ABC'))
df

   A  B  C
0  5  0  3
1  3  7  9
2  3  5  2
3  4  7  6
4  8  8  1

Logical AND

For df above, say you'd like to return all rows where A < 5 and B > 5. This is done by computing masks for each condition separately, and ANDing them.

Overloaded Bitwise & Operator
Before continuing, please take note of this particular excerpt of the docs, which state

Another common operation is the use of boolean vectors to filter the data. The operators are: | for or, & for and, and ~ for not. These must be grouped by using parentheses, since by default Python will evaluate an expression such as df.A > 2 & df.B < 3 as df.A > (2 & df.B) < 3, while the desired evaluation order is (df.A > 2) & (df.B < 3).

So, with this in mind, element wise logical AND can be implemented with the bitwise operator &:

df['A'] < 5

0    False
1     True
2     True
3     True
4    False
Name: A, dtype: bool

df['B'] > 5

0    False
1     True
2    False
3     True
4     True
Name: B, dtype: bool

(df['A'] < 5) & (df['B'] > 5)

0    False
1     True
2    False
3     True
4    False
dtype: bool

And the subsequent filtering step is simply,

df[(df['A'] < 5) & (df['B'] > 5)]

   A  B  C
1  3  7  9
3  4  7  6

The parentheses are used to override the default precedence order of bitwise operators, which have higher precedence over the conditional operators < and >. See the section of Operator Precedence in the python docs.

If you do not use parentheses, the expression is evaluated incorrectly. For example, if you accidentally attempt something such as

df['A'] < 5 & df['B'] > 5

It is parsed as

df['A'] < (5 & df['B']) > 5

Which becomes,

df['A'] < something_you_dont_want > 5

Which becomes (see the python docs on chained operator comparison),

(df['A'] < something_you_dont_want) and (something_you_dont_want > 5)

Which becomes,

# Both operands are Series...
something_else_you_dont_want1 and something_else_you_dont_want2

Which throws

ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

So, don't make that mistake!¹

Avoiding Parentheses Grouping
The fix is actually quite simple. Most operators have a corresponding bound method for DataFrames. If the individual masks are built up using functions instead of conditional operators, you will no longer need to group by parens to specify evaluation order:

df['A'].lt(5)

0     True
1     True
2     True
3     True
4    False
Name: A, dtype: bool

df['B'].gt(5)

0    False
1     True
2    False
3     True
4     True
Name: B, dtype: bool

df['A'].lt(5) & df['B'].gt(5)

0    False
1     True
2    False
3     True
4    False
dtype: bool

See the section on Flexible Comparisons.. To summarise, we have

+------------------------------+
¦    ¦ Operator   ¦ Function   ¦
¦----+------------+------------¦
¦  0 ¦ >          ¦ gt         ¦
+----+------------+------------¦
¦  1 ¦ >=         ¦ ge         ¦
+----+------------+------------¦
¦  2 ¦ <          ¦ lt         ¦
+----+------------+------------¦
¦  3 ¦ <=         ¦ le         ¦
+----+------------+------------¦
¦  4 ¦ ==         ¦ eq         ¦
+----+------------+------------¦
¦  5 ¦ !=         ¦ ne         ¦
+------------------------------+

Another option for avoiding parentheses is to use DataFrame.query (or eval):

df.query('A < 5 and B > 5')

   A  B  C
1  3  7  9
3  4  7  6

I have extensively documented query and eval in Dynamic Expression Evaluation in pandas using pd.eval().

operator.and_
Allows you to perform this operation in a functional manner. Internally calls Series.__and__ which corresponds to the bitwise operator.

import operator 

operator.and_(df['A'] < 5, df['B'] > 5)
# Same as,
# (df['A'] < 5).__and__(df['B'] > 5) 

0    False
1     True
2    False
3     True
4    False
dtype: bool

df[operator.and_(df['A'] < 5, df['B'] > 5)]

   A  B  C
1  3  7  9
3  4  7  6

You won't usually need this, but it is useful to know.

Generalizing: np.logical_and (and logical_and.reduce)
Another alternative is using np.logical_and, which also does not need parentheses grouping:

np.logical_and(df['A'] < 5, df['B'] > 5)

0    False
1     True
2    False
3     True
4    False
Name: A, dtype: bool

df[np.logical_and(df['A'] < 5, df['B'] > 5)]

   A  B  C
1  3  7  9
3  4  7  6

np.logical_and is a ufunc (Universal Functions), and most ufuncs have a reduce method. This means it is easier to generalise with logical_and if you have multiple masks to AND. For example, to AND masks m1 and m2 and m3 with &, you would have to do

m1 & m2 & m3

However, an easier option is

np.logical_and.reduce([m1, m2, m3])

This is powerful, because it lets you build on top of this with more complex logic (for example, dynamically generating masks in a list comprehension and adding all of them):

import operator

cols = ['A', 'B']
ops = [np.less, np.greater]
values = [5, 5]

m = np.logical_and.reduce([op(df[c], v) for op, c, v in zip(ops, cols, values)])
m 
# array([False,  True, False,  True, False])

df[m]
   A  B  C
1  3  7  9
3  4  7  6

_{1 - I know I'm harping on this point, but please bear with me. This is a very, very common beginner's mistake, and must be explained very thoroughly.}

Logical OR

For the df above, say you'd like to return all rows where A == 3 or B == 7.

Overloaded Bitwise |

df['A'] == 3

0    False
1     True
2     True
3    False
4    False
Name: A, dtype: bool

df['B'] == 7

0    False
1     True
2    False
3     True
4    False
Name: B, dtype: bool

(df['A'] == 3) | (df['B'] == 7)

0    False
1     True
2     True
3     True
4    False
dtype: bool

df[(df['A'] == 3) | (df['B'] == 7)]

   A  B  C
1  3  7  9
2  3  5  2
3  4  7  6

If you haven't yet, please also read the section on Logical AND above, all caveats apply here.

Alternatively, this operation can be specified with

df[df['A'].eq(3) | df['B'].eq(7)]

   A  B  C
1  3  7  9
2  3  5  2
3  4  7  6

operator.or_
Calls Series.__or__ under the hood.

operator.or_(df['A'] == 3, df['B'] == 7)
# Same as,
# (df['A'] == 3).__or__(df['B'] == 7)

0    False
1     True
2     True
3     True
4    False
dtype: bool

df[operator.or_(df['A'] == 3, df['B'] == 7)]

   A  B  C
1  3  7  9
2  3  5  2
3  4  7  6

np.logical_or
For two conditions, use logical_or:

np.logical_or(df['A'] == 3, df['B'] == 7)

0    False
1     True
2     True
3     True
4    False
Name: A, dtype: bool

df[np.logical_or(df['A'] == 3, df['B'] == 7)]

   A  B  C
1  3  7  9
2  3  5  2
3  4  7  6

For multiple masks, use logical_or.reduce:

np.logical_or.reduce([df['A'] == 3, df['B'] == 7])
# array([False,  True,  True,  True, False])

df[np.logical_or.reduce([df['A'] == 3, df['B'] == 7])]

   A  B  C
1  3  7  9
2  3  5  2
3  4  7  6

Logical NOT

Given a mask, such as

mask = pd.Series([True, True, False])

If you need to invert every boolean value (so that the end result is [False, False, True]), then you can use any of the methods below.

Bitwise ~

~mask

0    False
1    False
2     True
dtype: bool

Again, expressions need to be parenthesised.

~(df['A'] == 3)

0     True
1    False
2    False
3     True
4     True
Name: A, dtype: bool

This internally calls

mask.__invert__()

0    False
1    False
2     True
dtype: bool

But don't use it directly.

operator.inv
Internally calls __invert__ on the Series.

operator.inv(mask)

0    False
1    False
2     True
dtype: bool

np.logical_not
This is the numpy variant.

np.logical_not(mask)

0    False
1    False
2     True
dtype: bool

Note, np.logical_and can be substituted for np.bitwise_and, logical_or with bitwise_or, and logical_not with invert.

I moved VS Code from Downloads folder to Applications, and then i was able to run code in the terminal. I guess, it might help you too.

2 Options:

1. You want to exec a command from maven without binding to any phase, you just type the command and maven runs it, you just want to maven to run something, you don't care if we are in compile/package/... Let's say I want to run npm start with maven, you can achieve it with the below:

mvn exec:exec -Pstart-node

For that you need the below maven section

  <profiles>
    <profile>
      <id>start-node</id>
      <build>
        <plugins>
          <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>exec-maven-plugin</artifactId>
            <version>1.3.2</version>
            <executions>
              <execution>
                <goals>
                  <goal>exec</goal>
                </goals>
              </execution>
            </executions>
            <configuration>
              <executable>npm</executable>
              <arguments><argument>start</argument></arguments>
            </configuration>
          </plugin>
        </plugins>
      </build>
    </profile>

  </profiles>

2. You want to run an arbitrary command from maven while you are at a specific phase, for example when I'm at install phase I want to run npm install you can do that with:

mvn install

And for that to work you would need the below section:

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.3.2</version>
    <executions>

      <execution>
        <id>npm install (initialize)</id>
        <goals>
          <goal>exec</goal>
        </goals>
        <phase>initialize</phase>
        <configuration>
          <executable>npm</executable>
          <arguments>
            <argument>install</argument>
          </arguments>
        </configuration>
      </execution>

Functions containing no free variables are called pure functions.

Functions containing one or more free variables are called closures.

var pure = function pure(x){
  return x 
  // only own environment is used
}

var foo = "bar"

var closure = function closure(){
  return foo 
  // foo is a free variable from the outer environment
}

You can render the dependency tree with the command gradle dependencies. For more information check the section 11.6.4 Listing project dependencies in the online user guide.

Visual Studio 2017 is supported in Crystal Reports SP 21, which is available for download as of 1 Sep 2017.

In case you're already using the transform property for positioning your element (as I currently am), you can also animate the top margin:

.ball {
  animation: bounce 1s infinite alternate;
  -webkit-animation: bounce 1s infinite alternate;
}

@keyframes bounce {
  from {
    margin-top: 0;
  }
  to {
    margin-top: -15px;
  }
}

1. What exactly doesn't work?
2. Why are you using a 2d array?

3. If you must use a 2d array:

   int numOfPairs = 10;  String[][] array = new String[numOfPairs][2]; for(int i = 0; i < array.length; i++){     for(int j = 0; j < array[i].length; j++){         array[i] = new String[2];         array[i][0] = "original word";         array[i][1] = "rearranged word";     }    } 

Does this give you a hint?

There's a simple and fast solution using numpy by calculating mean squared error:

before = np.array(get_picture())
while True:
    now = np.array(get_picture())
    MSE = np.mean((now - before)**2)

    if  MSE > threshold:
        break

    before = now

Standard WCF Tracing/Diagnostics

If for some reason you are unable to get Fiddler to work, or would rather log the requests another way, another option is to use the standard WCF tracing functionality. This will produce a file that has a nice viewer.

You can't create a new branch with this command

git checkout --track origin/branch

if you have changes that are not staged.

Here is example:

$ git status
On branch master
Your branch is up to date with 'origin/master'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

        modified:   src/App.js

no changes added to commit (use "git add" and/or "git commit -a")

// TRY TO CREATE:

$ git checkout --track origin/new-branch
fatal: 'origin/new-branch' is not a commit and a branch 'new-branch' cannot be created from it

However you can easily create a new branch with un-staged changes with git checkout -b command:

$ git checkout -b new-branch
Switched to a new branch 'new-branch'
M       src/App.js

Status 2018:

There seems to be no way to place buttons (drawings, images) within cells in a way that would allow them to be linked to Apps Script functions.

This being said, there are some things that you can indeed do:

You can...

You can place images within cells using IMAGE(URL), but they cannot be linked to Apps Script functions.

You can place images within cells and link them to URLs using:
=HYPERLINK("http://example.com"; IMAGE("http://example.com/myimage.png"; 1))

You can create drawings as described in the answer of @Eduardo and they can be linked to Apps Script functions, but they will be stand-alone items that float freely "above" the spreadsheet and cannot be positioned in cells. They cannot be copied from cell to cell and they do not have a row or col position that the script function could read.

The str.split() method without an argument splits on whitespace:

>>> "many   fancy word \nhello    \thi".split()
['many', 'fancy', 'word', 'hello', 'hi']

Was just trying to write something simpler.

#!/usr/bin/python

from subprocess import Popen, PIPE
import datetime
import time 

popen = Popen(["/bin/sleep", "10"]);
pid = popen.pid
sttime = time.time();
waittime =  3

print "Start time %s"%(sttime)

while True:
    popen.poll();
    time.sleep(1)
    rcode = popen.returncode
    now = time.time();
    if [ rcode is None ]  and  [ now > (sttime + waittime) ] :
        print "Killing it now"
        popen.kill()

Escaping the double quotes with backslashes is the only way to do this in Java.

Some IDEs around such as IntelliJ IDEA do this escaping automatically when pasting such a String into a String literal (i.e. between the double quotes surrounding a java String literal)

One other option would be to put the String into some kind of text file that you would then read at runtime

    static void Main(string[] args)
    {
        AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;
    }

    static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
    {
        throw new NotImplementedException();
    }

For some reason, the replace works only with one string each time. I had a string like this "Test           MSP" and I want to leave only one space.

I used the approach that @Farhan did, but with some modifications:

CREATE FUNCTION ReplaceAll
(
    @OriginalString varchar(8000),
    @StringToRemove varchar(20),
    @StringToPutInPlace varchar(20)
)
RETURNS varchar(8000)
AS
BEGIN
declare @ResultStr varchar(8000)
set @ResultStr = @OriginalString
while charindex(@StringToRemove, @ResultStr) > 0
    set @ResultStr = replace(@ResultStr, @StringToRemove, @StringToPutInPlace)

return @ResultStr
END

Then I run my update like this

UPDATE tbTest SET Description = dbo.ReplaceAll(Description, '  ', ' ') WHERE ID = 14225

Then I got this result: Test MSP

Posting here if in case someone needs it as I did.

Running on: Microsoft SQL Server 2016 (SP2)

enum MyEnum
{  A_ENUM_VALUE=0,
   B_ENUM_VALUE,
   C_ENUM_VALUE
};


int main()
{
 printf("My enum Value : %d\n", (int)C_ENUM_VALUE);
 return 0;
}

You have just to cast enum to int !
Output : My enum Value : 2

From the "Zen of Assembly" by Abrash:

LEA, the only instruction that performs memory addressing calculations but doesn't actually address memory. LEA accepts a standard memory addressing operand, but does nothing more than store the calculated memory offset in the specified register, which may be any general purpose register.

What does that give us? Two things that ADD doesn't provide:

1. the ability to perform addition with either two or three operands, and
2. the ability to store the result in any register; not just one of the source operands.

And LEA does not alter the flags.

Examples

• LEA EAX, [ EAX + EBX + 1234567 ] calculates EAX + EBX + 1234567 (that's three operands)
• LEA EAX, [ EBX + ECX ] calculates EBX + ECX without overriding either with the result.
• multiplication by constant (by two, three, five or nine), if you use it like LEA EAX, [ EBX + N * EBX ] (N can be 1,2,4,8).

Other usecase is handy in loops: the difference between LEA EAX, [ EAX + 1 ] and INC EAX is that the latter changes EFLAGS but the former does not; this preserves CMP state.

It should be noted that the documentation recommends using a Layout rather than Canvas.drawText directly. My full answer about using a StaticLayout is here, but I will provide a summary below.

String text = "This is some text.";

TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
textPaint.setColor(0xFF000000);

int width = (int) textPaint.measureText(text);
StaticLayout staticLayout = new StaticLayout(text, textPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
staticLayout.draw(canvas);

Here is a fuller example in the context of a custom view:

public class MyView extends View {

    String mText = "This is some text.";
    TextPaint mTextPaint;
    StaticLayout mStaticLayout;

    // use this constructor if creating MyView programmatically
    public MyView(Context context) {
        super(context);
        initLabelView();
    }

    // this constructor is used when created from xml
    public MyView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initLabelView();
    }

    private void initLabelView() {
        mTextPaint = new TextPaint();
        mTextPaint.setAntiAlias(true);
        mTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
        mTextPaint.setColor(0xFF000000);

        // default to a single line of text
        int width = (int) mTextPaint.measureText(mText);
        mStaticLayout = new StaticLayout(mText, mTextPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);

        // New API alternate
        //
        // StaticLayout.Builder builder = StaticLayout.Builder.obtain(mText, 0, mText.length(), mTextPaint, width)
        //        .setAlignment(Layout.Alignment.ALIGN_NORMAL)
        //        .setLineSpacing(1, 0) // multiplier, add
        //        .setIncludePad(false);
        // mStaticLayout = builder.build();
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // Tell the parent layout how big this view would like to be
        // but still respect any requirements (measure specs) that are passed down.

        // determine the width
        int width;
        int widthMode = MeasureSpec.getMode(widthMeasureSpec);
        int widthRequirement = MeasureSpec.getSize(widthMeasureSpec);
        if (widthMode == MeasureSpec.EXACTLY) {
            width = widthRequirement;
        } else {
            width = mStaticLayout.getWidth() + getPaddingLeft() + getPaddingRight();
            if (widthMode == MeasureSpec.AT_MOST) {
                if (width > widthRequirement) {
                    width = widthRequirement;
                    // too long for a single line so relayout as multiline
                    mStaticLayout = new StaticLayout(mText, mTextPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
                }
            }
        }

        // determine the height
        int height;
        int heightMode = MeasureSpec.getMode(heightMeasureSpec);
        int heightRequirement = MeasureSpec.getSize(heightMeasureSpec);
        if (heightMode == MeasureSpec.EXACTLY) {
            height = heightRequirement;
        } else {
            height = mStaticLayout.getHeight() + getPaddingTop() + getPaddingBottom();
            if (heightMode == MeasureSpec.AT_MOST) {
                height = Math.min(height, heightRequirement);
            }
        }

        // Required call: set width and height
        setMeasuredDimension(width, height);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        // do as little as possible inside onDraw to improve performance

        // draw the text on the canvas after adjusting for padding
        canvas.save();
        canvas.translate(getPaddingLeft(), getPaddingTop());
        mStaticLayout.draw(canvas);
        canvas.restore();
    }
}

Here's the way I do it:

foo <- rnorm(100, mean=1, sd=2)
hist(foo, prob=TRUE)
curve(dnorm(x, mean=mean(foo), sd=sd(foo)), add=TRUE)

A bonus exercise is to do this with ggplot2 package ...

If you want to kill the Sticky Service,the following command NOT WORKING:

adb shell am force-stop <PACKAGE>
adb shell kill <PID>

The following command is WORKING:

adb shell pm disable <PACKAGE>

If you want to restart the app,you must run command below first:

adb shell pm enable <PACKAGE>

It is an implementation of Pythagorean theorem. Link: http://en.wikipedia.org/wiki/Pythagorean_theorem

Arduino sketches are written in C++.

Here is a typical construct you'll encounter:

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
...
lcd.begin(16, 2);
lcd.print("Hello, World!");

That's C++, not C.

Hence do yourself a favor and learn C++. There are plenty of books and online resources available.

Alternatively You can use the brew or curl command for installing things, wherever apt-get is mentioned with a URL...

For example,

curl -O http://www.magentocommerce.com/downloads/assets/1.8.1.0/magento-1.8.1.0.tar.gz

As pointed out by Max, you can't, but checking files modified or accessed is not all that hard. I wrote a tutorial about this, as late as today. The essence of which is to use -newerXY and ! -newerXY:

Example: To find all files modified on the 7th of June, 2007:

$ find . -type f -newermt 2007-06-07 ! -newermt 2007-06-08

To find all files accessed on the 29th of september, 2008:

$ find . -type f -newerat 2008-09-29 ! -newerat 2008-09-30

Or, files which had their permission changed on the same day:

$ find . -type f -newerct 2008-09-29 ! -newerct 2008-09-30

If you don't change permissions on the file, 'c' would normally correspond to the creation date, though.

There is a C# Google Voice API... there is limited documentation, however the download has an application that 'works' using the API that is included:

https://sourceforge.net/projects/gvoicedotnet/

We can also convert time into human-readable time.

import time, datetime

start = time.clock()

def num_multi1(max):
    result = 0
    for num in range(0, 1000):
        if (num % 3 == 0 or num % 5 == 0):
            result += num

    print "Sum is %d " % result

num_multi1(1000)

end = time.clock()
value = end - start
timestamp = datetime.datetime.fromtimestamp(value)
print timestamp.strftime('%Y-%m-%d %H:%M:%S')

You have a lot of type-mismatches in your code such as trying to put an int value where BigDecimal is required. The corrected version of your code:

public class Payment
{
    BigDecimal itemCost  = BigDecimal.ZERO;
    BigDecimal totalCost = BigDecimal.ZERO;

    public BigDecimal calculateCost(int itemQuantity, BigDecimal itemPrice)
    {
        itemCost  = itemPrice.multiply(new BigDecimal(itemQuantity));
        totalCost = totalCost.add(itemCost);
        return totalCost;
    }
}

My (simply) code (three months studying Python):

def more_frequent_item(lst):
    new_lst = []
    times = 0
    for item in lst:
        count_num = lst.count(item)
        new_lst.append(count_num)
        times = max(new_lst)
    key = max(lst, key=lst.count)
    print("In the list: ")
    print(lst)
    print("The most frequent item is " + str(key) + ". Appears " + str(times) + " times in this list.")


more_frequent_item([1, 2, 45, 55, 5, 4, 4, 4, 4, 4, 4, 5456, 56, 6, 7, 67])

The output will be:

In the list: 
[1, 2, 45, 55, 5, 4, 4, 4, 4, 4, 4, 5456, 56, 6, 7, 67]
The most frequent item is 4. Appears 6 times in this list.

To stick to == without consideration of the other type, the following is also possible.
type(a) == type(None)

You can't declare multiple types in the initialization, but you can assign to multiple types E.G.

{
   int i;
   char x;
   for(i = 0, x = 'p'; ...){
      ...
   }
}

Just declare them in their own scope.

Ids are meant to be unique, and never use an id that starts with a number, use data-attributes instead to set the target like so :

<div id="searchbycharacter">
    <a class="searchbychar" href="#" data-target="numeric">0-9 |</a> 
    <a class="searchbychar" href="#" data-target="A"> A |</a> 
    <a class="searchbychar" href="#" data-target="B"> B |</a> 
    <a class="searchbychar" href="#" data-target="C"> C |</a> 
    ... Untill Z
</div>

As for the jquery :

$(document).on('click','.searchbychar', function(event) {
    event.preventDefault();
    var target = "#" + this.getAttribute('data-target');
    $('html, body').animate({
        scrollTop: $(target).offset().top
    }, 2000);
});

And for webkit enabled browsers I've had good results with:

.myElement {
    -webkit-overflow-scrolling: touch;
    scroll-behavior: smooth; // Added in from answer from Felix
    overflow-x: scroll;
}

This makes scrolling behave much more like the standard browser behavior - at least it works well on the iPhone we were testing on!

Hope that helps,

Ed

Postgres Enterprise Manager from EnterpriseDB is probably the most advanced you'll find. It includes all the features of pgAdmin, plus monitoring of your hosts and database servers, predictive reporting, alerting and a SQL Profiler.

Ninja edit disclaimer/notice: it seems that this user is affiliated with EnterpriseDB, as the linked Postgres Enterprise Manager website contains a video of one Dave Page.

Here's my take on this:

if(object_id(N'[dbo].[fn_Nth_Pos]', N'FN')) is not null
    drop function [dbo].[fn_Nth_Pos];
GO
CREATE FUNCTION [dbo].[fn_Nth_Pos]
(
    @find char, --char to find
    @search varchar(max), --string to process   
    @nth int --occurrence   
)
RETURNS int
AS
BEGIN
    declare @pos int --position of nth occurrence
    --init
    set @pos = 0

    while(@nth > 0)
    begin       
        set @pos = charindex(@find,@search,@pos+1)
        set @nth = @nth - 1
    end 

    return @pos
END
GO

--EXAMPLE
declare @files table(name varchar(max));

insert into @files(name) values('abc_1_2_3_4.gif');
insert into @files(name) values('zzz_12_3_3_45.gif');

select
    f.name,
    dbo.fn_Nth_Pos('_', f.name, 1) as [1st],
    dbo.fn_Nth_Pos('_', f.name, 2) as [2nd],
    dbo.fn_Nth_Pos('_', f.name, 3) as [3rd],
    dbo.fn_Nth_Pos('_', f.name, 4) as [4th]
from 
    @files f;

Interfaces in C# are intended to define the contract that a class will adhere to - not a particular implementation.

In that spirit, C# interfaces do allow properties to be defined - which the caller must supply an implementation for:

interface ICar
{
    int Year { get; set; }
}

Implementing classes can use auto-properties to simplify implementation, if there's no special logic associated with the property:

class Automobile : ICar
{
    public int Year { get; set; } // automatically implemented
}

What is the __main__.py file for?

When creating a Python module, it is common to make the module execute some functionality (usually contained in a main function) when run as the entry point of the program. This is typically done with the following common idiom placed at the bottom of most Python files:

if __name__ == '__main__':
    # execute only if run as the entry point into the program
    main()

You can get the same semantics for a Python package with __main__.py, which might have the following structure:

.
+-- demo
    +-- __init__.py
    +-- __main__.py

To see this, paste the below into a Python 3 shell:

from pathlib import Path

demo = Path.cwd() / 'demo'
demo.mkdir()

(demo / '__init__.py').write_text("""
print('demo/__init__.py executed')

def main():
    print('main() executed')
""")

(demo / '__main__.py').write_text("""
print('demo/__main__.py executed')

from demo import main

main()
""")

We can treat demo as a package and actually import it, which executes the top-level code in the __init__.py (but not the main function):

>>> import demo
demo/__init__.py executed

When we use the package as the entry point to the program, we perform the code in the __main__.py, which imports the __init__.py first:

$ python -m demo
demo/__init__.py executed
demo/__main__.py executed
main() executed

You can derive this from the documentation. The documentation says:

__main__ — Top-level script environment

'__main__' is the name of the scope in which top-level code executes. A module’s __name__ is set equal to '__main__' when read from standard input, a script, or from an interactive prompt.

A module can discover whether or not it is running in the main scope by checking its own __name__, which allows a common idiom for conditionally executing code in a module when it is run as a script or with python -m but not when it is imported:

if __name__ == '__main__':
     # execute only if run as a script
     main()

For a package, the same effect can be achieved by including a __main__.py module, the contents of which will be executed when the module is run with -m.

Zipped

You can also zip up this directory, including the __main__.py, into a single file and run it from the command line like this - but note that zipped packages can't execute sub-packages or submodules as the entry point:

from pathlib import Path

demo = Path.cwd() / 'demo2'
demo.mkdir()

(demo / '__init__.py').write_text("""
print('demo2/__init__.py executed')

def main():
    print('main() executed')
""")

(demo / '__main__.py').write_text("""
print('demo2/__main__.py executed')

from __init__ import main

main()
""")

Note the subtle change - we are importing main from __init__ instead of demo2 - this zipped directory is not being treated as a package, but as a directory of scripts. So it must be used without the -m flag.

Particularly relevant to the question - zipapp causes the zipped directory to execute the __main__.py by default - and it is executed first, before __init__.py:

$ python -m zipapp demo2 -o demo2zip
$ python demo2zip
demo2/__main__.py executed
demo2/__init__.py executed
main() executed

Note again, this zipped directory is not a package - you cannot import it either.

This is what I use:

stat -f %N $your_path

You are trying to instantiate an interface, you need to give the concrete class that you want to use i.e. Queue<Edge> theQueue = new LinkedBlockingQueue<Edge>();.

There's one good reason not to use them: If you don't understand their role or how to use them.

In the wrong situations, foreign key constraints can lead to waterfall replication of accidents. If somebody removes the wrong record, undoing it can become a mammoth task.

Also, conversely, when you need to remove something, if poorly designed, constraints can cause all sorts of locks that prevent you.

It sounds like you want something like:

var query = from order in workOrders
            join plan in plans
                 on order.WorkOrderNumber equals plan.WorkOrderNumber
            select new
            {
                order.WorkOrderNumber,
                order.Description,
                plan.ScheduledDate
            };

Have a look at Stack Overflow question Python's “is” operator behaves unexpectedly with integers.

What it mostly boils down to is that "is" checks to see if they are the same object, not just equal to each other (the numbers below 256 are a special case).

Even if you could generate the PDF in-memory in JavaScript, you would still have the issue of how to transfer that data to the user. It's hard for JavaScript to just push a file at the user.

To get the file to the user, you would want to do a server submit in order to get the browser to bring up the save dialog.

With that said, it really isn't too hard to generate PDFs. Just read the spec.

Both attributes have been added to Bootstrap CDN to implement Subresource Integrity.

Subresource Integrity defines a mechanism by which user agents may verify that a fetched resource has been delivered without unexpected manipulation Reference

Integrity attribute is to allow the browser to check the file source to ensure that the code is never loaded if the source has been manipulated.

Crossorigin attribute is present when a request is loaded using 'CORS' which is now a requirement of SRI checking when not loaded from the 'same-origin'. More info on crossorigin

When you create a cookie via PHP die Default Value is 0, from the manual:

If set to 0, or omitted, the cookie will expire at the end of the session (when the browser closes)

Otherwise you can set the cookies lifetime in seconds as the third parameter:

http://www.php.net/manual/en/function.setcookie.php

But if you mean to get the remaining lifetime of an already existing cookie, i fear that, is not possible (at least not in a direct way).

I extended this question that is how to gets the row, columnand value of all matches value?

here is solution:

import pandas as pd
import numpy as np


def search_coordinate(df_data: pd.DataFrame, search_set: set) -> list:
    nda_values = df_data.values
    tuple_index = np.where(np.isin(nda_values, [e for e in search_set]))
    return [(row, col, nda_values[row][col]) for row, col in zip(tuple_index[0], tuple_index[1])]


if __name__ == '__main__':
    test_datas = [['cat', 'dog', ''],
                  ['goldfish', '', 'kitten'],
                  ['Puppy', 'hamster', 'mouse']
                  ]
    df_data = pd.DataFrame(test_datas)
    print(df_data)
    result_list = search_coordinate(df_data, {'dog', 'Puppy'})
    print(f"\n\n{'row':<4} {'col':<4} {'name':>10}")
    [print(f"{row:<4} {col:<4} {name:>10}") for row, col, name in result_list]

Output:

          0        1       2
0       cat      dog        
1  goldfish           kitten
2     Puppy  hamster   mouse


row  col        name
0    1           dog
2    0         Puppy

Try to rebuild openssl (if you are linking with it) with flag no-threads.

Are you sure you should be using POST not PUT?

POST is usually used with application/x-www-urlencoded formats. If you are using a REST API, you should maybe be using PUT? If you are uploading a file you probably need to use multipart/form-data. Not always, but usually, that is the right thing to do..

Also you don't seem to be using the credentials to log in - you need to use the Credentials property of the HttpWebRequest object to send the username and password.

Use defaultdict:

from collections import defaultdict

urls = defaultdict(int)

for url in list_of_urls:
    urls[url] += 1

As is mentioned, Agile is a methodology, and there are various ways to define what agile is. To a large extent, if it involves constant unit testing and the ability to quickly adapt when the business needs change then it is probably agile. The opposite is the waterfall method.

There are various implementations that are codified by consultants, such as Xtremem Programming, Scrum and RUP (Rational Unified Process).

So, if you are using Scrum then you can switch between agile and scrum depending on if you are talking about the methodology or your implementation. You will want to see if the terms are being used correctly, by the context.

For example, if I am talking about the 15 min standup as part of my agile process, that is not necessarily needed to be agile, but scrum almost requires it, so when you interchange the terms, it is important to differentiate between the two concepts.

One very nasty gotcha which just wasted a bit of my time debugging - you may find yourself prompted by auto-complete to try using doesContain which seems to work.

Except, doesContain uses an id comparison instead of the hash comparison used by objectForKey so if you have a dictionary with string keys it will return NO to a doesContain.

NSMutableDictionary* keysByName = [[NSMutableDictionary alloc] init];
keysByName[@"fred"] = @1;
NSString* test = @"fred";

if ([keysByName objectForKey:test] != nil)
    NSLog(@"\nit works for key lookups");  // OK
else
    NSLog(@"\nsod it");

if (keysByName[test] != nil)
    NSLog(@"\nit works for key lookups using indexed syntax");  // OK
else
    NSLog(@"\nsod it");

if ([keysByName doesContain:@"fred"])
    NSLog(@"\n doesContain works literally");
else
    NSLog(@"\nsod it");  // this one fails because of id comparison used by doesContain

Try this:

Open PgAdmin -> Files -> Open pgpass.conf

You would get the path of pgpass.conf at the bottom of the window. Go to that location and open this file, you can find your password there.

Reference

If the above does not work, you may consider trying this:

 1. edit pg_hba.conf to allow trust authorization temporarily
 2. Reload the config file (pg_ctl reload)
 3. Connect and issue ALTER ROLE / PASSWORD to set the new password
 4. edit pg_hba.conf again and restore the previous settings
 5. Reload the config file again

ASCII is in range of 0 to 127, so:

bradleygriffith's answer was great. I took step 10 and made a screenshot for simplification. This is a screenshot in Xcode 6.

1. Control-drag from the orange icon to the red Exit icon to create an unwind without any actions/buttons in the view.

2. Then select the unwind segue in the sidebar:

3. Set a Segue Identifier string:

4. Access that identifier from code:

[self performSegueWithIdentifier:@"unwindIdentifier" sender:self];

Just use the KeepAlive like @toster-cx says and then use the Socket Connected status to check if the Socket is still connected. Set your receive timeout at the same timeout of the keepalive. If you have more questions i am always happy to help!

nvarchar with preprocessing to standardize them as much as possible. You'll probably want to extract extensions and store them in another field.

You can execute:

$ mpicc -showme 

result :

gcc -I/Users/<USER_NAME>/openmpi-2.0.1/include -L/Users/<USER_NAME>/openmpi-2.0.1/lib -lmp

This command shows you the necessary libraries to compile mpicc

Example:

$ mpicc -g  -I/Users/<USER_NAME>/openmpi-2.0.1/include -o [nameExec] [objetcs.o...] [program.c] -lm


$ mpicc -g  -I/Users/<USER_NAME>/openmpi-2.0.1/include -o example file_object.o my_program.c otherlib.o -lm

this command generates executable with your program in example, you can execute :

$ ./example

What about?

If oSheet.QueryTables.Count > 0 Then
  oCmbBox.AddItem oSheet.Name
End If 

Or

If oSheet.ListObjects.Count > 0 Then
    '// Source type 3 = xlSrcQuery
    If oSheet.ListObjects(1).SourceType = 3 Then
         oCmbBox.AddItem oSheet.Name
    End IF
End IF

phihag's answer (and similar ones) won't work in python3.

For python 3:

d = {'key1': 1,'key2': 14,'key3': 47}
sum(list(d.values()))

Update! There are complains that it doesn't work! I just attach a screenshot from my terminal. Could be some mismatch in versions etc.

You can use display: table-cell property as in the following code:

div {
     height: 100%;
     display: table-cell; 
     vertical-align: middle;
    }

This is what I used when I had similar requirement. This determines the PID of the Java process correctly. Let your java code spawn a server on a pre-defined port number and then execute OS commands to find out the PID listening on the port. For Linux

netstat -tupln | grep portNumber

select OrderNo,PartCode,Quantity
from dbo.Test t1
WHERE EXISTS(SELECT 1
         FROM dbo.Test t2
         WHERE t2.OrderNo = t1.OrderNo
           AND t2.PartCode = t1.PartCode
         GROUP BY t2.OrderNo,
                  t2.PartCode
         HAVING t1.DateEntered = MAX(t2.DateEntered))

This is the fastest of all the queries supplied above. The query cost came in at 0.0070668.

The preferred answer above, by Mikael Eriksson, has a query cost of 0.0146625

You may not care about the performance for such a small sample, but in large queries, it all adds up.

I have used this CSS code and it worked for me:

html {
  height: 100%;
}
body {
  background: #f6cb4a; /* Old browsers */
  background: -moz-linear-gradient(top, #f2b600 0%, #f6cb4a 100%); /* FF3.6+ */
  background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#f2b600), color-stop(100%,#f6cb4a)); /* Chrome,Safari4+ */
  background: -webkit-linear-gradient(top, #f2b600 0%,#f6cb4a 100%); /* Chrome10+,Safari5.1+ */
  background: -o-linear-gradient(top, #f2b600 0%,#f6cb4a 100%); /* Opera 11.10+ */
  background: -ms-linear-gradient(top, #f2b600 0%,#f6cb4a 100%); /* IE10+ */
  background: linear-gradient(top, #f2b600 0%,#f6cb4a 100%); /* W3C */
  filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#f2b600', endColorstr='#f6cb4a',GradientType=0 ); /* IE6-9 */
  height: 100%;
  background-repeat: no-repeat;
  background-attachment: fixed;
  width: 100%;
  background-position: 0px 0px;
}

Here's a single line solution:

DateTime? d = DateTime.TryParse("text", out DateTime parseDate) ? parseDate : (DateTime?)null;

user@server:/etc/nginx$ cat .git/config 
...
[remote "origin"]
    url = [email protected]:user/.git
    fetch = +refs/heads/*:refs/remotes/origin/*
...

1. Use ssh instead of https.
2. To use ssh key in git (add ssh key).
3. If you are root, use the ssh key.

$ sudo ssh-keygen
$ cat /root/.ssh/id_rsa.pub 

$ git init
$ git add file
$ git commit -m "add first file"
$ git remote add origin [email protected]:user/example.git 
$ git push -u origin master

Sometime, I forget to copy library from Release-universal and mistakenly copy from Release-iphoneos. Usually Release-iphoneos contains .a file which has been pruned for X86. and so it gives the error.

You can use it in the same datafram (df) using the previously provided code

df[!grepl("REVERSE", df$Name),]

or you might assign a different name to the datafram using this code

df1<-df[!grepl("REVERSE", df$Name),]

In XMLHttpRequest, using XMLHttpRequest.responseText may raise the exception like below

 Failed to read the \'responseText\' property from \'XMLHttpRequest\': 
 The value is only accessible if the object\'s \'responseType\' is \'\' 
 or \'text\' (was \'arraybuffer\')

Best way to access the response from XHR as follows

function readBody(xhr) {
    var data;
    if (!xhr.responseType || xhr.responseType === "text") {
        data = xhr.responseText;
    } else if (xhr.responseType === "document") {
        data = xhr.responseXML;
    } else {
        data = xhr.response;
    }
    return data;
}

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
    if (xhr.readyState == 4) {
        console.log(readBody(xhr));
    }
}
xhr.open('GET', 'http://www.google.com', true);
xhr.send(null);

To remove the file from the index, use:

git reset myfile

This should not affect your local copy or anyone else's.

The xsd file is the schema of the xml file - it defines which elements may occur and their restrictions (like amount, order, boundaries, relationships,...)

(Context: My OS is Amazon linux using AWS. It seems similar to RedHat but it's stripped down a bit, it seems.)

Exit the shell, then open a new shell. The pip command now works.

That's what solved the problem at this location.

You might want to know as well: The pip commands to install software then needed to be written like this example (jupyter for example) to work correctly on my system:

pip install jupyter --user

Specifically, note the lack of sudo, and the presence of --user

Would be real nice if pip docs had said anything about all this, but that would take typing in more characters I guess.

For more advanced Go language scenarios, you can load an environment file, like this:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Launch",
      "type": "go",
      "request": "launch", 
      "mode": "debug",
      "remotePath": "",
      "port": 2345,
      "host": "127.0.0.1",
      "program": "${workspaceFolder}",
      "envFile": "${workspaceFolder}/.env",
      "args": [], 
      "showLog": true
    }
  ]
}

Place the .env file in your folder and add vars like this:

KEY1="TEXT_VAL1"
KEY2='{"key1":val1","key2":"val2"}'

Details: https://medium.com/@reuvenharrison/using-visual-studio-code-to-debug-a-go-program-with-environment-variables-523fea268271

You need to pass your context to your fyl class..
One solution is make a constructor like this for your fyl class:

public class fyl {
 Context mContext;
 public fyl(Context mContext) {
       this.mContext = mContext;
 }

 public Location getLocation() {
       --
       locationManager = (LocationManager)mContext.getSystemService(context);

       --
 }
}

So in your activity class create the object of fyl in onCreate function like this:

package com.atClass.lmt;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import android.location.Location;

public class lmt extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        fyl lfyl = new fyl(this); //Here the context is passing 

        Location location = lfyl.getLocation();
        String latLongString = lfyl.updateWithNewLocation(location);

        TextView myLocationText = (TextView)findViewById(R.id.myLocationText);
        myLocationText.setText("Your current position is:\n" + latLongString);
    }
}

For the allowed characters you can use

^[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$

to validate a complete string that should consist of only allowed characters. Note that - is at the end (because otherwise it'd be a range) and a few characters are escaped.

For the invalid characters you can use

[<>'"/;`%]

to check for them.

To combine both into a single regex you can use

^(?=[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$)(?!.*[<>'"/;`%])

but you'd need a regex engine that allows lookahead.

Here is the solution for Rest API

class Program
{
    static void Main(string[] args)
    {
        BaseClient clientbase = new BaseClient("https://website.com/api/v2/", "username", "password");
        BaseResponse response = new BaseResponse();
        BaseResponse response = clientbase.GetCallV2Async("Candidate").Result;
    }


    public async Task<BaseResponse> GetCallAsync(string endpoint)
    {
        try
        {
            HttpResponseMessage response = await client.GetAsync(endpoint + "/").ConfigureAwait(false);
            if (response.IsSuccessStatusCode)
            {
                baseresponse.ResponseMessage = await response.Content.ReadAsStringAsync();
                baseresponse.StatusCode = (int)response.StatusCode;
            }
            else
            {
                baseresponse.ResponseMessage = await response.Content.ReadAsStringAsync();
                baseresponse.StatusCode = (int)response.StatusCode;
            }
            return baseresponse;
        }
        catch (Exception ex)
        {
            baseresponse.StatusCode = 0;
            baseresponse.ResponseMessage = (ex.Message ?? ex.InnerException.ToString());
        }
        return baseresponse;
    }
}


public class BaseResponse
{
    public int StatusCode { get; set; }
    public string ResponseMessage { get; set; }
}

public class BaseClient
{
    readonly HttpClient client;
    readonly BaseResponse baseresponse;

    public BaseClient(string baseAddress, string username, string password)
    {
        HttpClientHandler handler = new HttpClientHandler()
        {
            Proxy = new WebProxy("http://127.0.0.1:8888"),
            UseProxy = false,
        };

        client = new HttpClient(handler);
        client.BaseAddress = new Uri(baseAddress);
        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        var byteArray = Encoding.ASCII.GetBytes(username + ":" + password);

        client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));

        baseresponse = new BaseResponse();

    }
}

CREATE DATABASE hindi_test

I have found this worked in the end (note the third line overriding the open function which find the button and hides it):

$("#div2").dialog({
    closeOnEscape: false,
    open: function(event, ui) {
        $(".ui-dialog-titlebar-close", ui.dialog || ui).hide();
    }
});

To hide the close button on all dialogs you can use the following CSS too:

.ui-dialog-titlebar-close {
    visibility: hidden;
}

Have you seen the FAQ entry What if I'm behind a proxy??

... edit your "servers" configuration file to indicate which proxy to use. The files location depends on your operating system. On Linux or Unix it is located in the directory "~/.subversion". On Windows it is in "%APPDATA%\Subversion". (Try "echo %APPDATA%", note this is a hidden directory.)

For me this involved uncommenting and setting the following lines:

#http-proxy-host=my.proxy
#http-proxy-port=80
#http-proxy-username=[username]
#http-proxy-password=[password]

On command line : nano ~/.subversion/servers

ApplicationId must be of type UniqueIdentifier. Your code works fine if you do:

DECLARE @TTEST TABLE
(
  TEST UNIQUEIDENTIFIER
)

DECLARE @UNIQUEX UNIQUEIDENTIFIER
SET @UNIQUEX = NEWID();

INSERT INTO @TTEST
(TEST)
VALUES
(@UNIQUEX);

SELECT * FROM @TTEST

Therefore I would say it is safe to assume that ApplicationId is not the correct data type.

You could just inline a generator to filter out the null values if you want to pretend they don't exist. Of course this is assuming the null bytes are not really part of the encoding and really are some kind of erroneous artifact or bug.

See the (line.replace('\0','') for line in f) below, also you'll want to probably open that file up using mode rb.

import csv

lines = []
with open('output.txt','r') as f:
    for line in f.readlines():
        lines.append(line[:-1])

with open('corrected.csv','w') as correct:
    writer = csv.writer(correct, dialect = 'excel')
    with open('input.csv', 'rb') as mycsv:
        reader = csv.reader( (line.replace('\0','') for line in mycsv) )
        for row in reader:
            if row[0] not in lines:
                writer.writerow(row)

You can use - matplotlib.gridspec.GridSpec

Check - https://matplotlib.org/stable/api/_as_gen/matplotlib.gridspec.GridSpec.html

The below code displays a heatmap on right and an Image on left.

#Creating 1 row and 2 columns grid
gs = gridspec.GridSpec(1, 2) 
fig = plt.figure(figsize=(25,3))

#Using the 1st row and 1st column for plotting heatmap
ax=plt.subplot(gs[0,0])
ax=sns.heatmap([[1,23,5,8,5]],annot=True)

#Using the 1st row and 2nd column to show the image
ax1=plt.subplot(gs[0,1])
ax1.grid(False)
ax1.set_yticklabels([])
ax1.set_xticklabels([])

#The below lines are used to display the image on ax1
image = io.imread("https://images-na.ssl-images- amazon.com/images/I/51MvhqY1qdL._SL160_.jpg")

plt.imshow(image)
plt.show()

Output image

In plain english a callback is a promise. Joe, Jane, David and Samantha share a carpool to work. Joe is driving today. Jane, David and Samantha have a couple of options:

1. Check the window every 5 minutes to see if Joe is out
2. Keep doing their thing until Joe rings the door bell.

Option 1: This is more like a polling example where Jane would be stuck in a "loop" checking if Joe is outside. Jane can't do anything else in the mean time.

Option 2: This is the callback example. Jane tells Joe to ring her doorbell when he's outside. She gives him a "function" to ring the door bell. Joe does not need to know how the door bell works or where it is, he just needs to call that function i.e. ring the door bell when he's there.

Callbacks are driven by "events". In this example the "event" is Joe's arrival. In Ajax for example events can be "success" or "failure" of the asynchronous request and each can have the same or different callbacks.

In terms of JavaScript applications and callbacks. We also need to understand "closures" and application context. What "this" refers to can easily confuse JavaScript developers. In this example within each person's "ring_the_door_bell()" method/callback there might be some other methods that each person need to do based on their morning routine ex. "turn_off_the_tv()". We would want "this" to refer to the "Jane" object or the "David" object so that each can setup whatever else they need done before Joe picks them up. This is where setting up the callback with Joe requires parodying the method so that "this" refers to the right object.

Hope that helps!

I faced the similar issue.

Deselect the check box ("In wizard deselect the checkbox stating "First row has columns names") and before running the wizard make sure you have opened your excel sheet.

Then run the wizard by deselecting the checkbox.

This resolved my issue.

As of this writing, in OS X, it will usually look like this

"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" --allow-file-access-from-files

If you are a freak like me, and put your apps in ~/Applications, then it will be

"/Users/yougohere/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" --allow-file-access-from-files

If neither of those are working, then type chrome://version in your Chrome address bar, and it will tell you what "command line" invocation you should be using. Just add --allow-file-access-from-files to that.

You could return the value using return JsonConvert.SerializeObject(objName); And send it to the front end

struct Node {
    int i;
    int j;
};
struct Node a, *p = &a;

Here the to access the values of i and j we can use the variable a and the pointer p as follows: a.i, (*p).i and p->i are all the same.

Here . is a "Direct Selector" and -> is an "Indirect Selector".

Use

rm -rf *

Update: The . stands for current directory, but we cannot use this. The command seems to have explicit checks for . and ... Use the wildcard globbing instead. But this can be risky.

A safer version IMO is to use:

rm -ri * 

(this prompts you for confirmation before deleting every file/directory.)

this should do:

//Main Class
public class SomeClass {

    //Sub-Class
    public static class AnotherClass {
        public enum MyEnum {
            VALUE_A, VALUE_B
        }    
        public MyEnum myEnum;
    }

    public void someMethod() { 
        AnotherClass.MyEnum enumExample = AnotherClass.MyEnum.VALUE_A; //...

        switch (enumExample) {
            case VALUE_A: { //<-- error on this line
            //..
            break;
            }
        }
    }
}

You might be better served by using a JavaScript framework, that has functions to return such information (and so much more!) in a browser-independant fashion. Here are a few:

• Prototype
• jQuery
• MooTools
• YUI (yahoo)

With these frameworks, you could do something like: $('id-of-img').top to get the y-pixel coordinate of the image.

After several tries, I got it! I'm setting the keyboard values programmatically like this:

myEditText.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD);

Or if you want you can edit the XML like so:

android: inputType = "numberPassword"

Both configs will display password bullets, so we need to create a custom ClickableSpan class:

private class NumericKeyBoardTransformationMethod extends PasswordTransformationMethod {
    @Override
    public CharSequence getTransformation(CharSequence source, View view) {
        return source;
    }
}

Finally we need to implement it on the EditText in order to display the characters typed.

myEditText.setTransformationMethod(new NumericKeyBoardTransformationMethod());

This is how my keyboard looks like now:

    SELECT DISTINCT
        ROW_NUMBER () OVER (ORDER BY pgc.relname , a.attnum) as rowid , 
        pgc.relname as table_name ,
        a.attnum as attr,
        a.attname as name,
        format_type(a.atttypid, a.atttypmod) as typ,
        a.attnotnull as notnull, 
        com.description as comment,
        coalesce(i.indisprimary,false) as primary_key,
        def.adsrc as default
    FROM pg_attribute a 
    JOIN pg_class pgc ON pgc.oid = a.attrelid
    LEFT JOIN pg_index i ON 
        (pgc.oid = i.indrelid AND i.indkey[0] = a.attnum)
    LEFT JOIN pg_description com on 
        (pgc.oid = com.objoid AND a.attnum = com.objsubid)
    LEFT JOIN pg_attrdef def ON 
        (a.attrelid = def.adrelid AND a.attnum = def.adnum)
    LEFT JOIN pg_catalog.pg_namespace n ON n.oid = pgc.relnamespace

What's new in Python 3.0 says:

All text is Unicode; however encoded Unicode is represented as binary data

If you want to ensure you are outputting utf-8, here's an example from this page on unicode in 3.0:

b'\x80abc'.decode("utf-8", "strict")

An integer value is a mathematical representation of a number and is ignorant of leading zeroes.

You can get a string with leading zeroes like this:

someNumber.ToString("00000000")

Also, you can do:

b = list(a)

This will work for any sequence, even those that don't support indexers and slices...

An in statement will be parsed identically to field=val1 or field=val2 or field=val3. Putting a null in there will boil down to field=null which won't work.

(Comment by Marc B)

I would do this for clairity

SELECT *
FROM tbl_name
WHERE 
(id_field IN ('value1', 'value2', 'value3') OR id_field IS NULL)

I came across this question and inspired by other contributors. I need to append some content to a file once per line. Here is what I did.

class Doh {
   def ln = System.getProperty('line.separator')
   File file //assume it's initialized 

   void append(String content) {
       file << "$content$ln"
   }
}

Pretty neat I think :)

You can achieve this using JQuery

HTML

 <input type="file" id="FilUploader" />

JQuery

    $("#FilUploader").change(function () {
        var fileExtension = ['jpeg', 'jpg', 'png', 'gif', 'bmp'];
        if ($.inArray($(this).val().split('.').pop().toLowerCase(), fileExtension) == -1) {
            alert("Only formats are allowed : "+fileExtension.join(', '));
        }
    });

Does it mean that I'm blocking reading any input from the Server/Client for this socket for 2000 millisecond and after this time the socket is ready to read data?

No, it means that if no data arrives within 2000ms a SocketTimeoutException will be thrown.

What does it mean timeout expire?

It means the 2000ms (in your case) elapses without any data arriving.

What is the option which must be enabled prior to blocking operation?

There isn't one that 'must be' enabled. If you mean 'may be enabled', this is one of them.

Infinite Timeout menas that the socket does't read anymore?

What a strange suggestion. It means that if no data ever arrives you will block in the read forever.

You can use CSS to hide the button.

button {
  visibility: hidden;
}

If your <button> is just a clickable area on the image, why bother make it a button? You can use <map> element instead.

The following solution works for me in TensorFlow 2.3 -

def load_pb(path_to_pb):
    with tf.io.gfile.GFile(path_to_pb, 'rb') as f:
        graph_def = tf.compat.v1.GraphDef()
        graph_def.ParseFromString(f.read())
    with tf.Graph().as_default() as graph:
        tf.import_graph_def(graph_def, name='')
        return graph

tf_graph = load_pb(MODEL_FILE)
sess = tf.compat.v1.Session(graph=tf_graph)

# Show tensor names in graph
for op in tf_graph.get_operations():
    print(op.values())

where MODEL_FILE is the path to your frozen graph.

Taken from here.

#include <cstdlib>
...
exit( exit_code );

What you need to do is to call pthread_mutex_lock to secure a mutex, like this:

pthread_mutex_lock(&mutex);

Once you do this, any other calls to pthread_mutex_lock(mutex) will not return until you call pthread_mutex_unlock in this thread. So if you try to call pthread_create, you will be able to create a new thread, and that thread will be able to (incorrectly) use the shared resource. You should call pthread_mutex_lock from within your fooAPI function, and that will cause the function to wait until the shared resource is available.

So you would have something like this:

#include <pthread.h>
#include <stdio.h>

int sharedResource = 0;
pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;

void* fooAPI(void* param)
{
    pthread_mutex_lock(&mutex);
    printf("Changing the shared resource now.\n");
    sharedResource = 42;
    pthread_mutex_unlock(&mutex);
    return 0;
}

int main()
{
    pthread_t thread;

    // Really not locking for any reason other than to make the point.
    pthread_mutex_lock(&mutex);
    pthread_create(&thread, NULL, fooAPI, NULL);
    sleep(1);
    pthread_mutex_unlock(&mutex);

    // Now we need to lock to use the shared resource.
    pthread_mutex_lock(&mutex);
    printf("%d\n", sharedResource);
    pthread_mutex_unlock(&mutex);
}

Edit: Using resources across processes follows this same basic approach, but you need to map the memory into your other process. Here's an example using shmem:

#include <stdio.h>
#include <unistd.h>
#include <sys/file.h>
#include <sys/mman.h>
#include <sys/wait.h>

struct shared {
    pthread_mutex_t mutex;
    int sharedResource;
};

int main()
{
    int fd = shm_open("/foo", O_CREAT | O_TRUNC | O_RDWR, 0600);
    ftruncate(fd, sizeof(struct shared));

    struct shared *p = (struct shared*)mmap(0, sizeof(struct shared),
        PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0);

    p->sharedResource = 0;

    // Make sure it can be shared across processes
    pthread_mutexattr_t shared;
    pthread_mutexattr_init(&shared);
    pthread_mutexattr_setpshared(&shared, PTHREAD_PROCESS_SHARED);

    pthread_mutex_init(&(p->mutex), &shared);

    int i;
    for (i = 0; i < 100; i++) {
        pthread_mutex_lock(&(p->mutex));
        printf("%d\n", p->sharedResource);
        pthread_mutex_unlock(&(p->mutex));
        sleep(1);
    }

    munmap(p, sizeof(struct shared*));
    shm_unlink("/foo");
}

Writing the program to make changes to p->sharedResource is left as an exercise for the reader. :-)

Forgot to note, by the way, that the mutex has to have the PTHREAD_PROCESS_SHARED attribute set, so that pthreads will work across processes.

As an extension to @LennartRegebro's answer:

If you can't tell what encoding your file uses and the solution above does not work (it's not utf8) and you found yourself merely guessing - there are online tools that you could use to identify what encoding that is. They aren't perfect but usually work just fine. After you figure out the encoding you should be able to use solution above.

EDIT: (Copied from comment)

A quite popular text editor Sublime Text has a command to display encoding if it has been set...

1. Go to View -> Show Console (or Ctrl+`)

2. Type into field at the bottom view.encoding() and hope for the best (I was unable to get anything but Undefined but maybe you will have better luck...)

DateTime.Now.ToString("M/d/yyyy");

An easy way of reaching a first intuition about what it's like is to imagine your program is a spreadsheet and all of your variables are cells. If any of the cells in a spreadsheet change, any cells that refer to that cell change as well. It's just the same with FRP. Now imagine that some of the cells change on their own (or rather, are taken from the outside world): in a GUI situation, the position of the mouse would be a good example.

That necessarily misses out rather a lot. The metaphor breaks down pretty fast when you actually use a FRP system. For one, there are usually attempts to model discrete events as well (e.g. the mouse being clicked). I'm only putting this here to give you an idea what it's like.

These variables are constants, i.e. private static final whether they're named in all caps or not. The all-caps convention simply makes it more obvious that these variables are meant to be constants, but it isn't required. I've seen

private static final Logger log = Logger.getLogger(MyClass.class);

in lowercase before, and I'm fine with it because I know to only use the logger to log messages, but it does violate the convention. You could argue that naming it log is a sub-convention, I suppose. But in general, naming constants in uppercase isn't the One Right Way, but it is The Best Way.

This is for vmware workstation 6.5

It is pretty far down.

select Create new virtual machine -> select custom ->
on compatibility page take defaults ->
check I will install os later -> click through several pages choosing other for OS, give it a name, make sure it IS NOT in the same folder as the VMDK file. Choose bridged network.

You will now see a screen asking to select disk, select existing virual disk. then browse and select the VMDK file

You don't really want to be reallocing memory every time you remove something. If you know the rough size of your deck then choose an appropriate size for your array and keep a pointer to the current end of the list. This is a stack.

If you don't know the size of your deck, and think it could get really big as well as keeps changing size, then you will have to do something a little more complex and implement a linked-list.

In C, you have two simple ways to declare an array.

1. On the stack, as a static array

   int myArray[16]; // Static array of 16 integers
   

2. On the heap, as a dynamically allocated array

   // Dynamically allocated array of 16 integers
   int* myArray = calloc(16, sizeof(int));
   

Standard C does not allow arrays of either of these types to be resized. You can either create a new array of a specific size, then copy the contents of the old array to the new one, or you can follow one of the suggestions above for a different abstract data type (ie: linked list, stack, queue, etc).

$user->data is an array of objects. Each element in the array has a name and value property (as well as others).

Try putting the 2nd foreach inside the 1st.

foreach($user->data as $mydata)
{
    echo $mydata->name . "\n";
    foreach($mydata->values as $values)
    {
        echo $values->value . "\n";
    }
}

You can try that one:

$string = preg_replace('/[^0-9]/', '', $string);

Cheers.

Very late to the thread, but a technique I've used, pre-Angular, is to take advantage of JSON and the flexibility of JS to dynamically reference collection keys, and use inalienable facts of the environment (host server name, current browser language, etc.) as inputs to selectively discriminate/prefer suffixed key names within a JSON data structure.

This provides not merely deploy-environment context (per OP) but any arbitrary context (such as language) to provide i18n or any other variance required simultaneously, and (ideally) within a single configuration manifest, without duplication, and readably obvious.

IN ABOUT 10 LINES VANILLA JS

Overly-simplified but classic example: An API endpoint base URL in a JSON-formatted properties file that varies per environment where (natch) the host server will also vary:

    ...
    'svcs': {
        'VER': '2.3',
        'API@localhost': 'http://localhost:9090/',
        '[email protected]': 'https://www.uat.productionwebsite.com:9090/res/',
        '[email protected]': 'https://www.productionwebsite.com:9090/api/res/'
    },
    ...

A key to the discrimination function is simply the server hostname in the request.

This, naturally, can be combined with an additional key based on the user's language settings:

    ...
    'app': {
        'NAME': 'Ferry Reservations',
        'NAME@fr': 'Réservations de ferry',
        'NAME@de': 'Fähren Reservierungen'
    },
    ...

The scope of the discrimination/preference can be confined to individual keys (as above) where the "base" key is only overwritten if there's a matching key+suffix for the inputs to the function -- or an entire structure, and that structure itself recursively parsed for matching discrimination/preference suffixes:

    'help': {
        'BLURB': 'This pre-production environment is not supported. Contact Development Team with questions.',
        'PHONE': '808-867-5309',
        'EMAIL': '[email protected]'
    },
    '[email protected]': {
        'BLURB': 'Please contact Customer Service Center',
        'BLURB@fr': 'S\'il vous plaît communiquer avec notre Centre de service à la clientèle',
        'BLURB@de': 'Bitte kontaktieren Sie unseren Kundendienst!!1!',
        'PHONE': '1-800-CUS-TOMR',
        'EMAIL': '[email protected]'
    },

SO, if a visiting user to the production website has German (de) language preference setting, the above configuration would collapse to:

    'help': {
        'BLURB': 'Bitte kontaktieren Sie unseren Kundendienst!!1!',
        'PHONE': '1-800-CUS-TOMR',
        'EMAIL': '[email protected]'
    },

What does such a magical preference/discrimination JSON-rewriting function look like? Not much:

// prefer(object,suffix|[suffixes]) by/par/durch storsoc
// prefer({ a: 'apple', a@env: 'banana', b: 'carrot' },'env') -> { a: 'banana', b: 'carrot' }
function prefer(o,sufs) {
    for (var key in o) {
        if (!o.hasOwnProperty(key)) continue; // skip non-instance props
        if(key.split('@')[1]) { // suffixed!
            // replace root prop with the suffixed prop if among prefs
            if(o[key] && sufs.indexOf(key.split('@')[1]) > -1) o[key.split('@')[0]] = JSON.parse(JSON.stringify(o[key]));

            // and nuke the suffixed prop to tidy up
            delete o[key];

            // continue with root key ...
            key = key.split('@')[0];
        }

        // ... in case it's a collection itself, recurse it!
        if(o[key] && typeof o[key] === 'object') prefer(o[key],sufs);

    };
};

In our implementations, which include Angular and pre-Angular websites, we simply bootstrap the configuration well ahead of other resource calls by placing the JSON within a self-executing JS closure, including the prefer() function, and fed basic properties of hostname and language-code (and accepts any additional arbitrary suffixes you might need):

(function(prefs){ var props = {
    'svcs': {
        'VER': '2.3',
        'API@localhost': 'http://localhost:9090/',
        '[email protected]': 'https://www.uat.productionwebsite.com:9090/res/',
        '[email protected]': 'https://www.productionwebsite.com:9090/api/res/'
    },
    ...
    /* yadda yadda moar JSON und bisque */

    function prefer(o,sufs) {
        // body of prefer function, broken for e.g.
    };

    // convert string and comma-separated-string to array .. and process it
    prefs = [].concat( ( prefs.split ? prefs.split(',') : prefs ) || []);
    prefer(props,prefs);
    window.app_props = JSON.parse(JSON.stringify(props));
})([location.hostname, ((window.navigator.userLanguage || window.navigator.language).split('-')[0])  ] );

A pre-Angular site would now have a collapsed (no @ suffixed keys) window.app_props to refer to.

An Angular site, as a bootstrap/init step, simply copies the dead-dropped props object into $rootScope, and (optionally) destroys it from global/window scope

app.constant('props',angular.copy(window.app_props || {})).run( function ($rootScope,props) { $rootScope.props = props; delete window.app_props;} );

to be subsequently injected into controllers:

app.controller('CtrlApp',function($log,props){ ... } );

or referred to from bindings in views:

<span>{{ props.help.blurb }} {{ props.help.email }}</span>

Caveats? The @ character is not valid JS/JSON variable/key naming, but so far accepted. If that's a deal-breaker, substitute for any convention you like, such as "__" (double underscore) as long as you stick to it.

The technique could be applied server-side, ported to Java or C# but your efficiency/compactness may vary.

Alternately, the function/convention could be part of your front-end compile script, so that the full gory all-environment/all-language JSON is never transmitted over the wire.

UPDATE

We've evolved usage of this technique to allow multiple suffixes to a key, to avoid being forced to use collections (you still can, as deeply as you want), and as well to honor the order of the preferred suffixes.

Example (also see working jsFiddle):

var o = { 'a':'apple', 'a@dev':'apple-dev', 'a@fr':'pomme',
          'b':'banana', 'b@fr':'banane', 'b@dev&fr':'banane-dev',
          'c':{ 'o':'c-dot-oh', 'o@fr':'c-point-oh' }, 'c@dev': { 'o':'c-dot-oh-dev', 'o@fr':'c-point-oh-dev' } };

/*1*/ prefer(o,'dev');        // { a:'apple-dev', b:'banana',     c:{o:'c-dot-oh-dev'}   }
/*2*/ prefer(o,'fr');         // { a:'pomme',     b:'banane',     c:{o:'c-point-oh'}     }
/*3*/ prefer(o,'dev,fr');     // { a:'apple-dev', b:'banane-dev', c:{o:'c-point-oh-dev'} }
/*4*/ prefer(o,['fr','dev']); // { a:'pomme',     b:'banane-dev', c:{o:'c-point-oh-dev'} }
/*5*/ prefer(o);              // { a:'apple',     b:'banana',     c:{o:'c-dot-oh'}       }

1/2 (basic usage) prefers '@dev' keys, discards all other suffixed keys

3 prefers '@dev' over '@fr', prefers '@dev&fr' over all others

4 (same as 3 but prefers '@fr' over '@dev')

5 no preferred suffixes, drops ALL suffixed properties

It accomplishes this by scoring each suffixed property and promoting the value of a suffixed property to the non-suffixed property when iterating over the properties and finding a higher-scored suffix.

Some efficiencies in this version, including removing dependence on JSON to deep-copy, and only recursing into objects that survive the scoring round at their depth:

function prefer(obj,suf) {
    function pr(o,s) {
        for (var p in o) {
            if (!o.hasOwnProperty(p) || !p.split('@')[1] || p.split('@@')[1] ) continue; // ignore: proto-prop OR not-suffixed OR temp prop score
            var b = p.split('@')[0]; // base prop name
            if(!!!o['@@'+b]) o['@@'+b] = 0; // +score placeholder
            var ps = p.split('@')[1].split('&'); // array of property suffixes
            var sc = 0; var v = 0; // reset (running)score and value
            while(ps.length) {
                // suffix value: index(of found suffix in prefs)^10
                v = Math.floor(Math.pow(10,s.indexOf(ps.pop())));
                if(!v) { sc = 0; break; } // found suf NOT in prefs, zero score (delete later)
                sc += v;
            }
            if(sc > o['@@'+b]) { o['@@'+b] = sc; o[b] = o[p]; } // hi-score! promote to base prop
            delete o[p];
        }
        for (var p in o) if(p.split('@@')[1]) delete o[p]; // remove scores
        for (var p in o) if(typeof o[p] === 'object') pr(o[p],s); // recurse surviving objs
    }
    if( typeof obj !== 'object' ) return; // validate
    suf = ( (suf || suf === 0 ) && ( suf.length || suf === parseFloat(suf) ) ? suf.toString().split(',') : []); // array|string|number|comma-separated-string -> array-of-strings
    pr(obj,suf.reverse());
}

Here is how I fixed this issue:

Open the nuget package manager console and install the below nuget packages:

Install-Package WebMatrix.Data
Install-Package Microsoft.AspNet.WebHelpers
Update-Package

Clean the solution, rebuild and my asp.net web app starts working!

You are right that this has long since been implemented in .NET Core.

At the time of writing (September 2019), the project.json file of NuGet 3.x+ has been superseded by PackageReference (as explained at https://docs.microsoft.com/en-us/nuget/archive/project-json).

To get access to the *Async methods of the HttpClient class, your .csproj file must be correctly configured.

Open your .csproj file in a plain text editor, and make sure the first line is
<Project Sdk="Microsoft.NET.Sdk.Web">
(as pointed out at https://docs.microsoft.com/en-us/dotnet/core/tools/project-json-to-csproj#the-csproj-format).

To get access to the *Async methods of the HttpClient class, you also need to have the correct package reference in your .csproj file, like so:

<ItemGroup>
    <!-- ... -->
    <PackageReference Include="Microsoft.AspNetCore.App" />
    <!-- ... -->
</ItemGroup>

(See https://docs.microsoft.com/en-us/nuget/consume-packages/package-references-in-project-files#adding-a-packagereference. Also: We recommend applications targeting ASP.NET Core 2.1 and later use the Microsoft.AspNetCore.App metapackage, https://docs.microsoft.com/en-us/aspnet/core/fundamentals/metapackage)

Methods such as PostAsJsonAsync, ReadAsAsync, PutAsJsonAsync and DeleteAsync should now work out of the box. (No using directive needed.)

Update: The PackageReference tag is no longer needed in .NET Core 3.0.

None of the existing answers worked for me, but this approach did.

The problem

I was seeing lots of cells say #REF!. These are cells in a sheet that I copied from another Google Sheet doc using "Copy to > Existing Worksheet". If I press Enter in any cell, it recalculates correctly, But I don't want to do that for millions of cells.

My answer

I ran this recalcSheet() script. It takes almost 0.5 seconds per cell, which is very slow but is faster than manually fixing each cell.

function recalcSheet(){  
  var spreadsheet = SpreadsheetApp.getActiveSpreadsheet()
  var sheet = spreadsheet.getSheetByName("put_your_sheet_name_here");  // https://developers.google.com/apps-script/reference/spreadsheet/spreadsheet#getsheetbynamename
  // var range = sheet.getSelection().getActiveRange();
  // var range = sheet.getRange('A6:D6');
  var range = sheet.getDataRange();  
  recalcRange(range, spreadsheet);
}

function recalcRange(range, spreadsheet){
  // following structure of https://stackoverflow.com/a/52123839/470749
  Logger.log('Range: ' + range.getA1Notation());
  var numRows = range.getNumRows();
  var numCols = range.getNumColumns();
  var startRow = range.getRow();
  var startCol = range.getColumn();
  Logger.log('row: ' + startRow);
  Logger.log('col: ' + startCol);
  Logger.log('numRows: ' + numRows);
  Logger.log('numCols: ' + numCols);

  for (var r = 1; r <= numRows; r+=1) {
    for (var c = 1; c <= numCols; c+=1) {
      var originalFormula = range.getCell(r, c).getFormula(); // https://developers.google.com/apps-script/reference/spreadsheet/range#getFormula()
      Logger.log(`r,c ${r}, ${c}; originalFormula: ${originalFormula}`);
      if(originalFormula){
        range.getCell(r, c).setFormula('');
        //SpreadsheetApp.flush(); // https://webapps.stackexchange.com/a/35970/27487
        range.getCell(r, c).setFormula(originalFormula);
      }
    }
  }
  spreadsheet.toast('Each cell in the range has been recalculated.', "Finished!"); // https://developers.google.com/apps-script/reference/spreadsheet/spreadsheet#toast(String)
}

=Sum(C:C)-Sum(C1:C5)

Sum everything then remove the sum of the values in the cells you don't want, no Volatile Offset's, Indirect's, or Array's needed.

Just for fun if you don't like that method you could also use:

=SUM($C$6:INDEX($C:$C,MATCH(9.99999999999999E+307,$C:$C))

The above formula will Sum only from C6 through the last cell in C:C where a match of a number is found. This is also non-volatile, but I believe more costly and sloppy. Just added it in case you'd prefer this anyways.

If you would like to do function like CountA for text using the last text value in a column you could use.

=COUNTIF(C6:INDEX($C:$C,MATCH(REPT("Z",255),$C:$C)),"T")

you could also use other combinations like:

=Sum($C$6:$C$65536) 

or

=CountIF($C$6:$C$65536,"T") 

The above would do what you ask in Excel 2003 and lower

=Sum($C$6:$C$1048576) 

or

=CountIF($C$6:$C$1048576,"T")

Would both work for Excel 2007+

All above functions would simply ignore all the blank values under the last value.

Hardware

If a GPU device has, for example, 4 multiprocessing units, and they can run 768 threads each: then at a given moment no more than 4*768 threads will be really running in parallel (if you planned more threads, they will be waiting their turn).

Software

threads are organized in blocks. A block is executed by a multiprocessing unit. The threads of a block can be indentified (indexed) using 1Dimension(x), 2Dimensions (x,y) or 3Dim indexes (x,y,z) but in any case xyz <= 768 for our example (other restrictions apply to x,y,z, see the guide and your device capability).

Obviously, if you need more than those 4*768 threads you need more than 4 blocks. Blocks may be also indexed 1D, 2D or 3D. There is a queue of blocks waiting to enter the GPU (because, in our example, the GPU has 4 multiprocessors and only 4 blocks are being executed simultaneously).

Now a simple case: processing a 512x512 image

Suppose we want one thread to process one pixel (i,j).

We can use blocks of 64 threads each. Then we need 512*512/64 = 4096 blocks (so to have 512x512 threads = 4096*64)

It's common to organize (to make indexing the image easier) the threads in 2D blocks having blockDim = 8 x 8 (the 64 threads per block). I prefer to call it threadsPerBlock.

dim3 threadsPerBlock(8, 8);  // 64 threads

and 2D gridDim = 64 x 64 blocks (the 4096 blocks needed). I prefer to call it numBlocks.

dim3 numBlocks(imageWidth/threadsPerBlock.x,  /* for instance 512/8 = 64*/
              imageHeight/threadsPerBlock.y); 

The kernel is launched like this:

myKernel <<<numBlocks,threadsPerBlock>>>( /* params for the kernel function */ );       

Finally: there will be something like "a queue of 4096 blocks", where a block is waiting to be assigned one of the multiprocessors of the GPU to get its 64 threads executed.

In the kernel the pixel (i,j) to be processed by a thread is calculated this way:

uint i = (blockIdx.x * blockDim.x) + threadIdx.x;
uint j = (blockIdx.y * blockDim.y) + threadIdx.y;

You can't do this with plain vanilla HTML, so JSF can't do much for you here as well.

If you're targeting decent browsers only, then just make use of CSS3:

.unselectable {
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

<label class="unselectable">Unselectable label</label>

If you'd like to cover older browsers as well, then consider this JavaScript fallback:

<!doctype html>
<html lang="en">
    <head>
        <title>SO question 2310734</title>
        <script>
            window.onload = function() {
                var labels = document.getElementsByTagName('label');
                for (var i = 0; i < labels.length; i++) {
                    disableSelection(labels[i]);
                }
            };
            function disableSelection(element) {
                if (typeof element.onselectstart != 'undefined') {
                    element.onselectstart = function() { return false; };
                } else if (typeof element.style.MozUserSelect != 'undefined') {
                    element.style.MozUserSelect = 'none';
                } else {
                    element.onmousedown = function() { return false; };
                }
            }
        </script>
    </head>
    <body>
        <label>Try to select this</label>
    </body>
</html>

If you're already using jQuery, then here's another example which adds a new function disableSelection() to jQuery so that you can use it anywhere in your jQuery code:

<!doctype html>
<html lang="en">
    <head>
        <title>SO question 2310734 with jQuery</title>
        <script src="http://code.jquery.com/jquery-latest.min.js"></script>
        <script>
            $.fn.extend({ 
                disableSelection: function() { 
                    this.each(function() { 
                        if (typeof this.onselectstart != 'undefined') {
                            this.onselectstart = function() { return false; };
                        } else if (typeof this.style.MozUserSelect != 'undefined') {
                            this.style.MozUserSelect = 'none';
                        } else {
                            this.onmousedown = function() { return false; };
                        }
                    }); 
                } 
            });

            $(document).ready(function() {
                $('label').disableSelection();            
            });
        </script>
    </head>
    <body>
        <label>Try to select this</label>
    </body>
</html>

Try to generate the proxy class via SvcUtil.exe with command

Syntax:

svcutil.exe /language:<type> /out:<name>.cs /config:<name>.config http://<host address>:<port>

Example:

svcutil.exe /language:cs /out:generatedProxy.cs /config:app.config http://localhost:8000/ServiceSamples/myService1

To check if service is available try in your IE URL from example upon without myService1 postfix

Here's the answer of how I achieve it:

Mylist.sort(Comparator.comparing(myClass::getStarttime));

You can use multiprocessing.Pool:

from multiprocessing import Pool
class Engine(object):
    def __init__(self, parameters):
        self.parameters = parameters
    def __call__(self, filename):
        sci = fits.open(filename + '.fits')
        manipulated = manipulate_image(sci, self.parameters)
        return manipulated

try:
    pool = Pool(8) # on 8 processors
    engine = Engine(my_parameters)
    data_outputs = pool.map(engine, data_inputs)
finally: # To make sure processes are closed in the end, even if errors happen
    pool.close()
    pool.join()

One option would be to put all the code in the loop inside a Sub and then just return from that Sub when you want to "continue".

Not perfect, but I think it would be less confusing that the extra loop.

I'm surprised this method hasn't been mentioned: "Some string".split(' ').shift()

To answer the question directly:

let firstWords = []
let str = "Hello m|sss sss|mmm ss";
const codeLines = str.split("|");

for (var i = 0; i < codeLines.length; i++) {
  const first = codeLines[i].split(' ').shift()
  firstWords.push(first)
}

I prefer

l.at(4)= -1;

while [4] is your index

This linker error usually (in my experience) means that you've overridden a virtual function in a child class with a declaration, but haven't given a definition for the method. For example:

class Base
{
    virtual void f() = 0;
}
class Derived : public Base
{
    void f();
}

But you haven't given the definition of f. When you use the class, you get the linker error. Much like a normal linker error, it's because the compiler knew what you were talking about, but the linker couldn't find the definition. It's just got a very difficult to understand message.

For me it was very important to get email logging working. After some time I discover that this need only 2 lines of code more in Atif example.

public class HandleErrorWithElmahAttribute : HandleErrorAttribute
{
    static ElmahMVCMailModule error_mail_log = new ElmahMVCMailModule();

    public override void OnException(ExceptionContext context)
    {
        error_mail_log.Init(HttpContext.Current.ApplicationInstance);
        [...]
    }
    [...]
}

I hope this will help someone :)

In my case the issue revealed to be chrome blocking the CORS request from localhost:4200 to facebook api website. Running Chrome with this setting: "YOUR_PATH_TO_CHROME\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="c:/chrome worked like a charm while developing. Even with no localhost added to facebook app's settings.

"N/A" is a string and cannot be converted to a number. Catch the exception and handle it. For example:

    String text = "N/A";
    int intVal = 0;
    try {
        intVal = Integer.parseInt(text);
    } catch (NumberFormatException e) {
        //Log it if needed
        intVal = //default fallback value;
    }

The Identator plugin works to me in Brackets Release 1.13 versión 1.13.0-17696 (release 49d29a8bc) on S.O. Windows 10

It wasn't specified in the original question (although I saw OP post in comments that this wasn't an option), but many developers on macOS have the Homebrew package manager installed.

For future developers who stumble upon this question, as long as the assumption (or requirement) of Homebrew being installed exists (e.g., in an engineering organization in a company), nproc is one of the common GNU binaries that is included in the coreutils package.

brew install coreutils

If you have scripts that you would prefer to write once (for Linux + macOS) instead of twice, or to avoid having if blocks where you need to detect the OS to know whether or not to call nproc vs sysctl -n hw.logicalcpu, this may be a better option.

if everything fails then for gmail you must turn on access to 3rd party apps to connect to ur gmail account.

https://www.google.com/settings/security/lesssecureapps // turn it on

U can find sample example here:

/**
     * Used to get the number of rows of the table
     * @param tableName
     * @param familyNames
     * @return the number of rows
     * @throws IOException
     */
    public long countRows(String tableName, String... familyNames) throws IOException {
        long rowCount = 0;
        Configuration configuration = connection.getConfiguration();
        // Increase RPC timeout, in case of a slow computation
        configuration.setLong("hbase.rpc.timeout", 600000);
        // Default is 1, set to a higher value for faster scanner.next(..)
        configuration.setLong("hbase.client.scanner.caching", 1000);

        AggregationClient aggregationClient = new AggregationClient(configuration);
        try {
            Scan scan = new Scan();
            if (familyNames != null && familyNames.length > 0) {
                for (String familyName : familyNames) {
                    scan.addFamily(Bytes.toBytes(familyName));
                }
            }
            rowCount = aggregationClient.rowCount(TableName.valueOf(tableName), new LongColumnInterpreter(), scan);
        } catch (Throwable e) {
            throw new IOException(e);
        }
        return rowCount;
    }

I think what you're seeing is the hiding and showing of scrollbars. Here's a quick demo showing the width change.

As an aside: do you need to poll constantly? You might be able to optimize your code to run on the resize event, like this:

$(window).resize(function() {
  //update stuff
});

Start menu → Accessories → right click on "Command prompt". In the menu, click "Run as Administrator" (on Windows XP you can just run it as usual), run netstat -anb, and then look through output for your program.

BTW, Skype by default tries to use ports 80 and 443 for incoming connections.

You can also run netstat -anb >%USERPROFILE%\ports.txt followed by start %USERPROFILE%\ports.txt to open the port and process list in a text editor, where you can search for the information you want.

You can also use PowerShell to parse netstat output and present it in a better way (or process it any way you want):

$proc = @{};
Get-Process | ForEach-Object { $proc.Add($_.Id, $_) };
netstat -aon | Select-String "\s*([^\s]+)\s+([^\s]+):([^\s]+)\s+([^\s]+):([^\s]+)\s+([^\s]+)?\s+([^\s]+)" | ForEach-Object {
    $g = $_.Matches[0].Groups;
    New-Object PSObject |
        Add-Member @{ Protocol =           $g[1].Value  } -PassThru |
        Add-Member @{ LocalAddress =       $g[2].Value  } -PassThru |
        Add-Member @{ LocalPort =     [int]$g[3].Value  } -PassThru |
        Add-Member @{ RemoteAddress =      $g[4].Value  } -PassThru |
        Add-Member @{ RemotePort =         $g[5].Value  } -PassThru |
        Add-Member @{ State =              $g[6].Value  } -PassThru |
        Add-Member @{ PID =           [int]$g[7].Value  } -PassThru |
        Add-Member @{ Process = $proc[[int]$g[7].Value] } -PassThru;
#} | Format-Table Protocol,LocalAddress,LocalPort,RemoteAddress,RemotePort,State -GroupBy @{Name='Process';Expression={$p=$_.Process;@{$True=$p.ProcessName; $False=$p.MainModule.FileName}[$p.MainModule -eq $Null] + ' PID: ' + $p.Id}} -AutoSize
} | Sort-Object PID | Out-GridView

Also it does not require elevation to run.

Note that you must use asynchronous calls for spinners to work (at least that is what caused mine to not show until after the ajax call and then swiftly went away as the call had finished and removed the spinner).

$.ajax({
        url: requestUrl,
        data: data,
        dataType: 'JSON',
        processData: false,
        type: requestMethod,
        async: true,                         <<<<<<------ set async to true
        accepts: 'application/json',
        contentType: 'application/json',
        success: function (restResponse) {
            // something here
        },
        error: function (restResponse) {
            // something here                
        }
    });

It returns the file contents length

First the computer looks up the destination host. If it exists in local DNS cache, it uses that information. Otherwise, DNS querying is performed until the IP address is found.

Then, your browser opens a TCP connection to the destination host and sends the request according to HTTP 1.1 (or might use HTTP 1.0, but normal browsers don't do it any more).

The server looks up the required resource (if it exists) and responds using HTTP protocol, sends the data to the client (=your browser)

The browser then uses HTML parser to re-create document structure which is later presented to you on screen. If it finds references to external resources, such as pictures, css files, javascript files, these are is delivered the same way as the HTML document itself.

I am using Oracle SQL Developer,

In this tool, I had to enable DBMS output to view the results printed by dbms_output.put_line

You can find this option in the result pane where other query results are displayed. so, in the result pane, I have 7 tabs. 1st tab named as Results, next one is Script Output and so on. Out of this you can find a tab named as "DBMS Output" select this tab, then the 1st icon (looks like a dialogue icon) is Enable DBMS Output. Click this icon. Then you execute the PL/SQL, then select "DBMS Output tab, you should be able to see the results there.

This is an old thread but just in case anyone comes across it like I did. pi.FileName needs to be set to the file name (and possibly full path to file ) of the executable you want to use to open your file. The below code works for me to open a video file with VLC.

var path = files[currentIndex].fileName;
var pi = new ProcessStartInfo(path)
{
    Arguments = Path.GetFileName(path),
    UseShellExecute = true,
    WorkingDirectory = Path.GetDirectoryName(path),
    FileName = "C:\\Program Files (x86)\\VideoLAN\\VLC\\vlc.exe",
    Verb = "OPEN"
};
Process.Start(pi)

Tigran's answer works but will use windows' default application to open your file, so using ProcessStartInfo may be useful if you want to open the file with an application that is not the default.

You can use thread_pool from boost library:

void my_task(){...}

int main(){
    int threadNumbers = thread::hardware_concurrency();
    boost::asio::thread_pool pool(threadNumbers);

    // Submit a function to the pool.
    boost::asio::post(pool, my_task);

    // Submit a lambda object to the pool.
    boost::asio::post(pool, []() {
      ...
    });
}

You also can use threadpool from open source community:

void first_task() {...}    
void second_task() {...}

int main(){
    int threadNumbers = thread::hardware_concurrency();
    pool tp(threadNumbers);

    // Add some tasks to the pool.
    tp.schedule(&first_task);
    tp.schedule(&second_task);
}

To me the solution was just deleted the specific folder which is giving the error from ~/.m2/repository/org/hsqldb/

After deleting the hsqldb folder I have build the project and everything is fine.

Session

Session is used for maintaining a dialogue between server and user. It is more secure because it is stored on the server, we cannot easily access it. It embeds cookies on the user computer. It stores unlimited data.

Cookies

Cookies are stored on the local computer. Basically, it maintains user identification, meaning it tracks visitors record. It is less secure than session. It stores limited amount of data, and is maintained for a limited time.

I'm using MySQL 5.5.19.

I like having scripts that you can run and rerun without error, especially where warnings seem to linger, showing up again later while I'm running scripts that have no errors/warnings. As far as adding fields goes, I wrote myself a procedure to make it a little less typing:

-- add fields to template table to support ignoring extra data 
-- at the top/bottom of every page
CALL addFieldIfNotExists ('template', 'firstPageHeaderEndY', 'INT NOT NULL DEFAULT 0');
CALL addFieldIfNotExists ('template', 'pageHeaderEndY', 'INT NOT NULL DEFAULT 0');
CALL addFieldIfNotExists ('template', 'pageFooterBeginY', 'INT NOT NULL DEFAULT 792');

The code to create the addFieldIfNotExists procedure is as follows:

DELIMITER $$

DROP PROCEDURE IF EXISTS addFieldIfNotExists 
$$

DROP FUNCTION IF EXISTS isFieldExisting 
$$

CREATE FUNCTION isFieldExisting (table_name_IN VARCHAR(100), field_name_IN VARCHAR(100)) 
RETURNS INT
RETURN (
    SELECT COUNT(COLUMN_NAME) 
    FROM INFORMATION_SCHEMA.columns 
    WHERE TABLE_SCHEMA = DATABASE() 
    AND TABLE_NAME = table_name_IN 
    AND COLUMN_NAME = field_name_IN
)
$$

CREATE PROCEDURE addFieldIfNotExists (
    IN table_name_IN VARCHAR(100)
    , IN field_name_IN VARCHAR(100)
    , IN field_definition_IN VARCHAR(100)
)
BEGIN

    -- http://javajon.blogspot.com/2012/10/mysql-alter-table-add-column-if-not.html

    SET @isFieldThere = isFieldExisting(table_name_IN, field_name_IN);
    IF (@isFieldThere = 0) THEN

        SET @ddl = CONCAT('ALTER TABLE ', table_name_IN);
        SET @ddl = CONCAT(@ddl, ' ', 'ADD COLUMN') ;
        SET @ddl = CONCAT(@ddl, ' ', field_name_IN);
        SET @ddl = CONCAT(@ddl, ' ', field_definition_IN);

        PREPARE stmt FROM @ddl;
        EXECUTE stmt;
        DEALLOCATE PREPARE stmt;

    END IF;

END;
$$

I didn't write a procedure to safely modify a column, but I think the above procedure could be easily modified to do so.

JSON parsing using NSJSONSerialization

   NSString* path  = [[NSBundle mainBundle] pathForResource:@"data" ofType:@"json"];
   
    //Here you can take JSON string from your URL ,I am using json file
    NSString* jsonString = [[NSString alloc] initWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
    NSData* jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
    NSError *jsonError;
    NSArray *jsonDataArray = [NSJSONSerialization JSONObjectWithData:[jsonString dataUsingEncoding:NSUTF8StringEncoding] options:kNilOptions error:&jsonError];
  
    NSLog(@"jsonDataArray: %@",jsonDataArray);

    NSDictionary *jsonObject = [NSJSONSerialization JSONObjectWithData:jsonData options:kNilOptions error:&jsonError];
if(jsonObject !=nil){
   // NSString *errorCode=[NSMutableString stringWithFormat:@"%@",[jsonObject objectForKey:@"response"]];
   
        
        if(![[jsonObject objectForKey:@"#data"] isEqual:@""]){
            
            NSMutableArray *array=[jsonObject objectForKey:@"#data"];
             // NSLog(@"array: %@",array);
            NSLog(@"array: %d",array.count);  
            
            int k = 0;
            for(int z = 0; z<array.count;z++){
                
                NSString *strfd = [NSString stringWithFormat:@"%d",k];
                NSDictionary *dicr = jsonObject[@"#data"][strfd];
                k=k+1;
                // NSLog(@"dicr: %@",dicr);
                 NSLog(@"Firstname - Lastname   : %@ - %@",
                     [NSMutableString stringWithFormat:@"%@",[dicr objectForKey:@"user_first_name"]],
                     [NSMutableString stringWithFormat:@"%@",[dicr objectForKey:@"user_last_name"]]);
            }
            
          }

     }

You can see the Console output as below :

Firstname - Lastname : Chandra Bhusan - Pandey

Firstname - Lastname : Kalaiyarasan - Balu

Firstname - Lastname : (null) - (null)

Firstname - Lastname : Girija - S

Firstname - Lastname : Girija - S

Firstname - Lastname : (null) - (null)

Just for reference, if you are using:

 $(el).offset().top 

To get the position, it can be affected by the position of the parent element. Thus you may want to be consistent and use the following to set it:

$(el).offset({top: pos});

As opposed to the CSS methods above.

The CSS uses only the data in the DOM tree, which has little to do with how the renderer decides what to do with elements with missing attributes.

So either let the CSS reflect the HTML

input:not([type]), input[type="text"]
{
background:red;
}

or make the HTML explicit.

<input name='t1' type='text'/> /* Is Not Red */

If it didn't do that, you'd never be able to distinguish between

element { ...properties... }

and

element[attr] { ...properties... }

because all attributes would always be defined on all elements. (For example, table always has a border attribute, with 0 for a default.)

Swift 3+

NSLog(@"%@", decodedString); // foo 

Alternatively, you can use the File.GetCreationTime Method if you need to delete files based on creation dates.

I would like to share my way of starting chrome - specificaly youtube tv - in full screen mode automatically, without the need of pressing F11. kiosk/fullscreen options doesn't seem to work (Version 41.0.2272.89). It has some steps though...

• Start chrome and navigate to page (www.youtube.com/tv)
• Drag the address from the address bar (the lock icon) to the desktop. It will create a shortcut.
• From chrome, open Apps (the icon with the multiple coloured dots)
• From desktop, drag the shortcut into the Apps space
• Right click on the new icon in Apps and select "Open fullscreen"
• Right click again on the icon in Apps and select "Create shortcuts..."
• Select for example Desktop and Create. A new shortcut will be created on desktop.

Now, whenever you click on this shortcut, chrome will start in fullscreen and at the page you defined. I guess you can put this shortcut in startup folder to run when windows starts, but I haven't tried it.

That's a byte order mark, as everyone says.

javac does not understand the BOM, not even when you try something like

javac -encoding UTF8 Test.java

You need to strip the BOM or convert your source file to another encoding. Notepad++ can convert a single files encoding, I'm not aware of a batch utility on the Windows platform for this.
